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.

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!

It’s very hard to remove them at once they adhere to the car body.
They affect the car paint surface badly.

We also mentioned about pollen and yellow sand detail below;
【https://pikarain.asia/blog/blog/this-is-the-thorough-countermeasures-three-ways-to-protect-your-car-from-pollen-and-yellow-sand/】

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

Finally

However, the durable is much better than other car wax or coating.
(We don’t know any other more durable coating…)

Protect your car from scratches! Solutions and precautions!

How do I protect my precious car from scratches?

The one of big problems standing in the way of keeping cars beautiful is…

Ssratches.

“My car got scratches while I’m driving car!”
Some of you happens by your mistake like above.
For these scratches, you can prevent some of them by your cautions.

However, actually almost all of scratches on the car body which is impossible to prevent completely.
For example, scratches which are got in driving, taking off, due to weather and animals… it is impossible to control all of them even though you are be careful.

However, you don’t drive your car not to get scratches, do you?

Then, how do we deal with them?
This time we would like to introduce about the reasons, solutions and precautions for each.

Don’t underestimate scratches! If you leave them…

We said just “scratches” when we explained, but there are many types.
In this section, we would like to explain about its differences and each fears.

■Clawing

These are lines like cat’s nail marks.
There are possibility to get these when some hard materials like a coin or key hit the car body.
Around a doorknob are many small scratches because drivers take out and put in the key.
If the scratches are not so serious, you can deal with them by some easy ways such polishing and applying car coating (to hide them).

■Scrapping

These are for wide area.
Have you ever seen a white car which has black grazes slightly on the corner?
The car gets these when the car scraped the wall or obstacles (electric light poles, crash barriers, vegetation …etc.) or crash two cars.
These can be recovered by polishing, too.

■Sands / stepping-stones

It cannot help making scratches when you drive by sands and stepping-stones.
Regard as sands, these could be scratches during car wash.
Regard as steeping-stones, these could damage the car paint surface when these hit to the car body.
For the parts which get whitish by stepping-stones, please recover with a touch pen yourself or ask professionals for serious ones.

■Dents

The battered car body by the huge impact.
Sometimes these can be recovered when you pat from the other side, but if the dents are serious, there is possibility to exchange all parts.
However, sometimes the paint surface comes off even the dents are not serious and in this case, repainting is also necessary.

■Damages

These are more serious and wider than dents.
Of course it looks bad and you should better to deal with it as soon as possible for safety and maintenance.

■Rust

If you leave the water on scratches or iron fillings, it becomes rust.
Not only brown rust adhere to the car paint surfaces, but also it is eaten by rust if you leave for a long time.
Before rusting, it is possible to recover with chemical products such as an iron fillings remover or a rust remover.
(However, please make sure that it depends on the situation, so you might need puttying or repainting.)

A polishing machine can solve many types of scratches!


If you try to remove scratches which cannot be removed by washing by force, the car body will damage.

Of course there are removers in the market, but it is troublesome if you use different products for different types of dirt.

Someone who wants to make whole of the car body beautiful quickly, we would like to recommend polishing which is using compound and a polishing machine.

Some car waxes in the market content compound, so these can be one way to remove slight scratches, but it depends on the color, so if you own different colors cars, it should be costly.

Moreover, almost all of car wax is only for polishing by hands, if the dirt is expanding, the work must be so hard and applying only car wax is not so durable.

Therefore, you need to reapply the car wax regularly, so polishing the car body with compound is faster for removing scratches.

Then when you polish the car body with compound, we would like to recommend using a polishing machine than polishing by hands.

If the scratches are partial and removable by polishing with compound a little, polishing by hands would be fine, but if you polish the same parts for a long time by force, there is a high risk such polished too much or color irregularity due to friction.

If you use a polishing machine, you can polish evenly and can finish the work much faster than polishing by hands.

However, you have to be careful when you use a polisher, too.
First if you don’t have enough experiences of using a polishing machine, you should better to use a “double-action” type.

In fact, a polishing machine which is used by professionals is a “single-action” type which has stronger power.
But it is difficult to handle, so there is possibility to polish the car body too much. Therefore, we wouldn’t like to recommend it for beginners.

A “double-action” type can move up and down, left and right. It is difficult to get scratches and the friction heat can be cut down.

You can get a polishing machine at a home centers, so please consider about it when you apply compound.

Let’s reduce the damage to the car body by ceramic coating!

Let’s protect your precious car from damages by applying ceramic coating.

There are many good points of ceramic coating.
It can last the beautiful condition at once you apply you don’t have to apply it many times like car wax.
Moreover, the water repellency will get better, so it will be difficult to adhere water spots after raining. Also washing dirt off and drying will get easier, too.

In this section, we would like to explain how to apply Pika Pika Rain Ceramic Coating.

1. Washing

The first step is basic car washing.
Please splash the water to the car and wash adhered dirt and dust off.
Then please wash it with car shampoo.
At this time, please wash with a soft microfiber cloth not to damage to the car body.

2. Preparation

Next, let’s check the car condition!
If you start applying even though scratches and dirt remain on the car body, they will be coated all together, so please do preparation and clean your car.
If there are any scratches and water spots, you can skip this step.

As we said above, compound is an ideal tool for scratches.
Please polish scratches and water spots and make the car body beautiful.

3. Removing oil

Pleaser remove the oil on the car body with Pika Pika Rain Oil Remover.
It is not necessary, but we would like to recommend to do this, because Pika Pika Rain Oil Remover makes fixing much better even though a brand new car.

4. Applying ceramic coating

Finally, you can start to apply ceramic coating after above steps.
Please put a few drops of Pika Pika Rain Ceramic Coating liquid (only for the beginning, about 6 drops) on a sponge and spread it thinly.
After you applied, wiped the liquid with a microfiber cloth.
If you don’t wipe well can be reason of foggy finishing, so please check the results well during wiping.

Also please repeat this step in every small parts.
If apply it widely at one time, the liquid dry before wiping and it is easy to be fogy finishing, so you have to be careful.

Above is how to apply Pika Pika Rain Ceramic Coating.

However, there is one thing which you should be careful.
Please make sure that you don’t have to wash your car anymore even though you applied ceramic coating.
If you leave your car without car washing, dirt on the glass layer cannot be removed. Also if you leave it after raining, the water which remain on the car body could be water spots…

Therefore please don’t forget that car washing is necessary even though you applied ceramic coating.

Moreover, please don’t misunderstand that your car won’t get scratches anymore.
It cannot help getting scratches to the ceramic coating if you drive your car in your daily life. (Of course, the car body can be protected by the ceramic coating.)

The performance will get lower than when you applied it when your car got scratches.
Please apply the ceramic coating with your understanding about it!

Got scratches on the ceramic coating! What should we do?
Ceramic coating has a hard layer, but it cannot help getting scratches.
First, trying not to get them is important, but we would like to introduce solutions when your car gets them!

Be careful at the following situations

■Cautions for car washing

Please wash rough dirt with a plenty of water.
If you wash a car with a microfiber cloth or a sponge which has rough dirt on the car body, the rough dirt is drug and it causes scratches.

Also please use a soft cloth as much as possible. A microfiber cloth is the best.

Finally, please wash your car by hands as much as you can.
If you wash it with a mop or a car wash machine it got slight scratches due to stepping-stones.
If you have to use a car wash machine at any cost, a high pressure car wash machine is fine.

■Cautions for applying ceramic coating

Please don’t apply the ceramic coating by force.
Ceramic coating is different from car wax, so it is better to imagine that making another layer on the car body.
Applying it by force causes scratches.
You don’t have to apply Pika Pika Rain Ceramic Coating by force in the all steps.

If the ceramic coating get scratches…

■For slight scratches

For slight scratches, reapplication of ceramic coating is recommended.
Ceramic coating doesn’t have an effect of removing scratches, but the liquid is filled up in unevenness parts, so it can make the scratches less noticeable.

■For deep scratches

For scratches which reach to the clear layer, it is difficult to hide by ceramic coating.
In this case, removing scratches is the only way.
However, if you polish with compound, the ceramic coating is polished together.
You should better to reapply it to the parts which you polished.
By the way, if scratches are very deep such reach to the car paint surface cannot be removed by polishing with compound.
