Must-see how to deal with failures according to case!

When you think that you failed in application…

Regard as steps of Pika Pika Rain Ceramic Coating application are…

applying the solution with a sponge,


wiping it with a microfiber cloth.

This simplicity is one of our attractiveness.
However, sometimes you might failed in application.
Also there could be various reasons such as mistakes yourself or unavoidable events.

In this article, we would like to introduce how to deal with them by each cases!

Case no.1 : Applied to the glass or rubber parts!

In the first place, why Pika Pika Rain Ceramic Coating cannot be applied to thems?
Some of you might think that it seems OK as it can be applied to plastic.

We understand your question!
Now, we would like to explain about the reasons.

Regard as glass parts

Frankly, the main reason is not effective.

Pika Pika Rain Ceramic Coating changes to 100% glass after hardening.
Therefore, it means applying glass (coating) to glass (parts)…
Of course, it could protect the glass parts and repel the water, but you could not be impressed by the results as the car body.

Moreover, glass is clear and it is the difficult part to find foggy results.
Sometimes our customers want to apply it to the glass roof,
but we always answer that it’s OK, but please apply carefully more than the car body.
(Recovery when you failed is much more difficult than car body, too!)

Regard as rubber parts

First, the solution will be absorbed too much.
Also please make sure that there is a possibility to change the color.
Some carbon, metal and chromyl parts as well.
Frankly, it is a very rare case, but Pika Pika Rain Ceramic Coating is made for the clear layer,
so please test to unnoticeable parts first definitely when you wonder whether I can apply or not.

Rubber is a shrinking part, so there is a possibility to become worse as stop its shrinking by ceramic coating.

An Extra article: regard as a sticker and a decal

We also ask our customers to avoid applying Pika Pika Rain Ceramic Coating to a sticker or a decal.
Because the solution is “liquid” before it harden.
That is to say these get weaker to stick as they absorbed the liquid.

Therefore, if you want to use a sticker or decal,
please apply Pika Pika Rain Ceramic Coating and protect the paint surface first, and then enjoy your decoration!


However, failures are part of DIY coating.
We would like to explain how to deal with below.
Please make note that some cases are difficult to deal with, so you should better to use a masking tape before application if you want!

For glass parts

・Please wipe the solution with a microfiber cloth if just after the solution adhered.
・After full hardening and if you can find foggy results obviously, you should polish with a compound for windows.
※Windows are very easy to get damages. Please use only for glass compound definitely.

For rubber parts

・Please wipe the solution with a microfiber cloth immediately if just after the solution adhered.
・When the solution has already get stained, it’s difficult to recover.


We have already mentioned in the article of rubber parts application,
please test to unnoticeable areas firs when you apply Pika Pika Rain Ceramic Coating to a car which in a bad condition or full painted.

Of course, almost all you can apply it without failures,
but Pika Pika Rain Ceramic Coating follows the foundation, so it can last longer if the foundation is as much as good condition.

Case no.2 : Began raining suddenly!

Pika Pika Rain Ceramic Coating doesn’t allow to get after 12 hours application.
If you are parking your car outside, please pay attention to “rain”.
Especially, you should be carefully more.

What will happen if the car caught in the rain?

If you leave the rain on the Pika Pika Rain Ceramic Coating which is before full-hardening, it causes foggy results and dirt.
Otherwise, the coating will be removed by raining.

How to deal with

【Before Pika Pika Rain Ceramic Coating hardening】

When it rains during application, please move your car to the other place where has a roof.
After that please wipe the water with a microfiber cloth.

If you are not able to do it, please stop applying immediately.
Then wipe the water on the car body with a microfiber cloth softly.

Using a cover is also fine.
Please use it after you wipe the water as much as you can.
Also please be careful not to rub against the car body and take it off as soon as possible. There is possibility to make hardening time longer as it doesn’t allow air to pass through well.

【During Pika Pika Rain Ceramic Coating hardening】

Hardening will be finished in its own way after a few hours application even before 12 hours.
In this condition, hardly ceramic coating will not be removed even it rains.

However, the time of hardening depends on the circumstances or weather, so please wipe the water drops with a microfiber cloth after raining.

If it becomes white or foggy, the glass layer forms onto the car body, so you don’t have to be worried about it.

【After Pika Pika Rain Ceramic Coating hardening】

After 12 hours application, it’s OK even the car body gets wet.
Please deal with as below if you find dirt or foggy due to rain.

・Before hardening
Wipe the solution with a microfiber cloth.

・During hardening
Polish with a compound and remove the glass layer.
After washing partially, reapply the area with the left solution.

Case no.3 : The coating became foggy!

Sometimes we had inquires “There are foggy areas when I checked the car body after application!”

You might apply ceramic coating to make your car beautifully, but at once the coating gets foggy, it looks bad.
Moreover, it could not perform its water repellency and gloss completely.

Then, we would like to explain about the reason to prevent this problem

Why does the ceramic coating get foggy?

1. Wiping the solution are not enough.

You should better to apply in to against this problem.
If you apply after sunset or in a dark place such as a garage, you tend to overlook even you cannot apply completely.

2. Drying the solution

In summer, the solution dries so quickly.
Then you could not spread the solution well and it causes foggy results.

3. Preparation is not enough

If you apply ceramic coating to a dirty car, the thickness of glass layer changes sporadically and the areas tend to be foggy.
At once the dirt is covered with the glass layer, you just have to remove it by polishing.
Therefore, let’s do preparation carefully.

4. Getting wet within 12 hours application

If the ceramic coating gets wet during this period, it hardens unstably.
Please check the weather forecast and set the schedule well.

How to deal with

Next, we would like to explain how to deal with foggy results.

・Before hardening
This case is that you noticed soon after you applied the solution.
You can spread the solution and easily in this case.
It is the easiest to deal with in this step, so please check by many angles during application.

・During hardening
In this case, the solution doesn’t harden completely,
so please apply the additional solution to the area and wipe it.
It’s OK if all foggy areas disappear when you check.

In case of after 12 hours application, polish them and apply the foggy area again.
If you reapply without polishing, the foggy area will be covered the new glass layer.

Case no.4 : Others

When you applied the solution too much thinly

“I might use the solution too much…”
“Somewhere I didn’t apply…”

If you worried like above, we would like to recommend the second application!

The step is just applying after full-hardening same as the first time.
(※Keeping the bottle in a cool and dark place such as a refrigerator is highly recommended.)
(※At once you open the bottle, the solution has started hardening. Please check whether the solution becomes white or crystals and use it on your own responsibility.)

Preparation is important for ceramic coating

For a brand new car, you don’t have to need preparation especially – car wash and removing oil are enough.
However, if your car is dirty or has already applied other coating, you need preparation.

If scratches or water spots are serious

Please polish with a compound to remove them.
If the area is small, using Water Spots Remover is available.
Using a polisher is highly recommended for polishing the wide area.

If your car has already applied other car wax or coating

If the car wax or coating are not strong which can be remover by daily car wash,
you should apply Pika Pika Rain Ceramic Coating after the old glass layer removed completely.

If you apply Pika Pika Rain Ceramic Coating onto another car wax or coating, there is possibility to become non-durable, so we would like to use Oil Remover just in case.

If the car wax or coating are strong which cannot be removed by daily car wash, please removed it with a compound.


How was it?

If you have already failed in application, we’re happy to try like above, but you want to prevent against them previously, don’t you?

Finally, we would like to explain about the tips.

Check the weather forecast and set the application day

We understand that we’ve already mentioned it many times, but Pika Pika Rain Ceramic Coating doesn’t allow to get after 12 hours application.
Therefore, please choose the sunny days for application and the next day.
To postpone the application is one of good ways such as a rainy season.

Apply the solution thinly and evenly!

“Is the solution enough for a whole car such a small bottle?”

We usually get inquiries from customers above.
However, you don’t have to be worried about it.
Pika Pika Rain Ceramic Coating spreads very well, so many amount doesn’t.

We understand you tend to use the solution too much, but it is completely different.
Please make sure that applying and wiping thinly!
Also we have a movie how to apply, it could be better you watch it and check the steps of application in advance.

“My problem doesn’t come under above cases!”
“I don’ find solutions even I study much!”

If you have any questions, please feel free to ask us with an email!

Scratches by stepping stones and water spots by rain as well.
Water spots are white, so these are so remarkable on the dark color body.

Moreover, it depends on areas, in the season of yellow sand and pollen, your car gets whitish within a half day…

Then, we would like to recommend applying ceramic coating to reduce damages!

From now, we would like to introduce about advantages for ceramic coating application!

“Regular car washing is essential for any types of cars”
We mentioned about advantages for applying ceramic coating to dark color, light color and solid color cars above.

Ceramic coating can reduce damages and dirt on the paint surface.
However, only ceramic coating is not perfect.

For example, you leave your car for long time after ceramic coating application.
Then dirt (also water spots if you park outside) increase cumulatively on the glass layer.
Naturally, the dirt noticeable and the anti-dirt power gets down.

Then, what should we do?

The answer is regular car washing.
Of course, it is a common thing regardless of the body colors.

Tips for car wash

You might understand the importance of car wash.

Next, we would like to explain about tips for car wash.
It is “wiping”.

Please do it as a finishing.

If you forget wiping after car wash, the water remained on the car body will change to stubborn water spots.
Almost of all water spots cannot be removed by washing, so you need to polish with compound.
(Using a polisher is recommended for the wide area.)
Polishing is a hard work, so you should better to wipe water completely.

Moreover, we recommend to use a microfiber cloth for wiping.
(Please make sure that you cannot reuse the microfiber cloth which you used for ceramic coating application!)

“Wipe the water gently with a microfiber cloth after car wash”
Don’t forget this word!

Let’s keep the gloss and water repellency of ceramic coating for a long time by daily car care!

Cherish your precious car more by ceramic coating

We would like to talk about ceramic coating to ride cherish your precious car.

First is the looking.
We believe that some of you who have applied car ceramic coating agree with this.
The car body between before and after ceramic coating application is totally different.
It has beautiful gloss, so when you compare with unapplied car, you should smile with the difference.

Ceramic coating doesn’t have a glossy like car wax, but the glass layer is clear,
so we can recommend it to you who want to enjoy its original color.
(However, please make sure that it will make a mat color, too.)

For a dark color car or a solid color car which has attractive vivid colors, fading the color is one of the biggest problems.
However, any paint surfaces cannot deal with deterioration.
Especially, a car which are parking outside tends to fade its color rapidly due to the sunlight.

Ceramic coating can make deterioration slowly a little.
Because the main reason is ultra violet, but ceramic coating has a short wavelength, so there is possibility to reflect by the thin layer such a ceramic coating.
Then it leads to car paint protection.

Our conclusion: Applying ceramic coating is not meaningless for every cars!

How was it?
Even same term of ceramic coating, advantages depend on body colors.

To reduce scratches for a dark color car.
To save the time for car wash and reduce fading the color for a bright color car.

We believe that you understand applying ceramic coating is not for every cars.

Moreover, Pika Pika Rain Ceramic Car Coating can be applied to any types of cars such as light, dark or solid colors!
(Please make note that only for the car which has a clear coat.)

We’re happy that you confirm this article when you’re thinking about ceramic coating application.

How long does the car glass coating take for hardening?

Car glass coting needs time for hardening.

One of the features of car glass coating (which means the solution changes to glass) is long durability, not like car wax or simplified coating.
It cannot be removed by raining or daily car wash, so it can protect your precious car for a long time.

However, on the other hand, it takes longer time for hardening than other coating.
Then, why does it need a time for hardening?

This time, we would like to explain about the reason, hardening time, and cautions while hardening!

The reason why car ceramic coating needs time for hardening?

・Comparison of glass coating and other coating or wax

Let’s compare 100% real glass coating and others in hardening.

【Wax & polymer】

They cover the car body after drying.
Almost all of them dry within from 30 minutes to 1 hours completely.
However, it doesn’t adhere to the car paint surface, just put on the car body, so it is not durable.
It can be removed by car washing and raining.

【Glass coating】

At one the solution expose to the air, hardening is starting gradually.
Regard as the components, please see the below.

It takes 12 hours to the surface harden.

After it harden fully, it adheres to the car paint surface, so we cannot make a revision.
Therefore, we need to use a polisher if we want to remove the glass layer.
The strong glass layer perform the long durability.

How does the glass coating produced?

One of the biggest Pika Pika Rain Glass Coating’s selling points are hardening, but many people might not know how the solution in the bottle produce to the glass.

Then, in this section, we would like to explain the theory with an example of Pika Pika Rain Glass Coating.

The main components after applying are glass and alcohol.
At this time, it isn’t 100% glass, because there are alcohol and other things as impurities.
However, when the solution expose to the air, the hydrolytic happens.
We’re afraid to say that details are company secret, but after hydrolytic, alcohol + α volatilized and the remained com are “100% glass layer”.
Long hardening time is related to this theory.

Moreover, after that, the car paint surface and glass layer will adhere gradually for 2 weeks.
At once they adhere, it won’t be removed by washing and deterioration.
It can protect the car body with the durable glass layer.

“Why don’t you apply 100% glass solution? Why do you take a difficult containing?”
Some people might think like above, but 100% glass is very same glass like a windshield.

Please imagine… it is impossible to apply the glass, isn’t it?
That’s why application with the solution which has high glass leve; is difficult.

The difference between surface hardening and full hardening

We’ve already explained above, the glass coating needs a long time to cure fully.

For example, in case of Pika Pika Rain Glass Coating,
After 12 hours application for their surface hardening and 2 weeks for full hardening.

Please see these difference below.

About surface hardening

It means that the glass coating solution which applied to the car body is on the way of hardening the glass coating solution.
Also it is very sensitive in this period.

In case of Pika Pika Rain Glass Coating, first the glass coating solution reacts chemically with the water in the air, and it harden gradually.

It doesn’t harden from the inside of the solution, harden from the surface which exposed to the air slowly.

About full hardening

It means that the glass coating is finished as the solution harder fully and adhere to the paint surface.
From application to finished hardening takes for about 2 weeks.
After full hardening, you can do washing and caring as usual.

Nano Pika Pika Rain application and the second layer application are available after full hardening.

We heard that some detailers keep customers’ car for a few weeks and wait for full hardening.

If you don’t want to keep your car anymore after you got it, please take this opportunity to try DIY glass coating application!
Pika Pika Rain Glass Coating doesn’t have to keep your car to detailers as you can drive after surface hardening (after 12hours application).

Cautions while under hardening

Next, we would like to introduce cautions after you applied the glass coating.

Cautions for surface hardening
The glass coating stars surface hardening after 2 hours application, and it will finish within 12 hours.
In this period, please make sure
“not to get wet”, “not to drive” and “not to use a cover”.

Do not allow your car get wet for 12 hours after application!

It also include rain, night and morning dew.
Also please do not wash your car in this period.

However, we understand that all people don’t keep their car in a garage, and it rains suddenly while application.
Then, what should we do in these cases?

If your car gets wet, please move your car to other place which has a roof.
After that please wipe the water with a microfiber cloth gently.

Avoid driving

If you drive your car after application, the glass layer will be removed by stepping stones,
or there is possibility to gets dirty due to dust.

Therefore, please avoid driving if it’s essential such as suddenly raining or keeping the car in the different place.

Avoid using a cover

If you use a cover before the glass coating harden completely, there is possibility to remove the glass coating when you take on and take of the cover.

However, sometimes we have inquiries from our customers,
“I want to use a cover because I don’t deal with raining immediately!”

As we have already mentioned, we don’t recommend to use a cover.
Because, if you leave your car after raining for a long time, the glass layer become foggy and you need to polish with a compound if it it’s serious.
Please decide yourself in view of above risks.

How deal with foggy areas while surface hardening?

First, please wipe the area with a microfiber cloth.
Even though it cannot be removed, please apply left glass coating solution to the foggy area with a sponge and spread it with another microfiber cloth.

Cautions while full hardening

When the surface hardening finished (12 hours), after 2 weeks is a period of full hardening.
Regard as cautions in this period,
“do not leave the water for a long time”.

Do not leave the water for a long time

It is not so strict such as the surface hardening, but, the water which you left for a long time causes water spots.
Therefore, if it starts to rain, please wipe the water on the car body with a microfiber cloth softly.

You can car wash your car in this period.
However, please make note that washing with hand, not using a car wash machine.

How deal with foggy areas while full hardening?

Hardening has already started, so you should polish with a compound if you remove foggy areas. Then you wash your car the area and apply again with a left solution.

If you’re planning reapplication, you should better wait until the area harden fully and reapply whole a car.

After full hardening

Now, we would like to explain about glass coating results on the car body in detail.

Point 1. Gloss

First of all, you can find beautiful gloss particular to glass coating!

Your precious car gets amazing gloss like a brand new car!
Of course, a brand new car get deeper and more beautiful.

You become attached to your precious car more if it is glossy, and daily driving could be more fun.
We often heard from our customers who tend to indulge in a sense of their superiorities when your car is shiner than other cars in a car park.

Point 2. Water repellency

Before application, usually the water remains on the car body and it causes water spots, and it also wiping is time-consuming.

However, you don’t have same trouble at once your car body was applied by Pika Pika Rain Glass Coating!
Its water repellency is outstanding!
The water is sliding, so wiping get easier that before application!

Point 3. Anti-dirt power

Pika Pika Rain Glass Coating has nice anti-dirt power, too!
As we said above, the water sliding, so there are less risks for water spots.

Also the car body gets dirty by mud in rainy days.
However, you don’t worried about it anymore!
Dirt can be removed easily due to the glass coating.
Only washing with the water is fine for light dirt! It decrease effort for wiping.

It can be measures for pollen or yellow sand, too!

Do you know that they are harmful to your precious car?
It’s very hard to remove them at once they adhere to the car body.
They affect the car paint surface badly.

However, Pika Pika Rain Glass Coating can protect from they, so you don’t have to be worried about the damage to the car paint surface.

We also mentioned about pollen and yellow sand detail below;

Do you understand the good points of glass coating?
It needs 2 weeks until the glass layer harden fully, but durability is 3 years!


After all, car glass coating take a long time for hardening!
However, the durable is much better than other car wax or coating.
(We don’t know any other more durable coating…)

“I worried about raining while hardening…”
“I don’t want to take a time for application!”

If you think like above, we would like to recommend simplified coating or car wax, but if you don’t want applying again and again, or want to keep your precious car in beautiful condition, we would like real glass coating.

Please follow right application ways and have a nice car life!
