Please check before application…

Pika Pika Rain’s glass coating liquid cures fast, and that process is not like waxing.

Therefore, we should apply the liquid area by are like the picture below:

Please work in bright light to find the surface evenly applied.

1. Application

Pika Pika Rain’s application sponge

Our application sponge is comparatively small because it’s designed to fit with tiny parts like wheel or backside of knob. You never miss to apply small parts. We designed this 2 layers sponge based on professional detailers review.

Where to apply Pika Pika Rain

Pika Pika Rain’s glass coating liquid is available to metallic part like iron, steel and copper, also available to plastic parts like headlight.

Tricks and tips for application

Basic method of application is to apply thinly and evenly. Only with 2-3 drops, Pika Pika Rain spreads very well. You need more drops if the sponge is squeaky and doesn’t move smoothly. When you start to apply first, a few drops should be better. Then, apply the liquid line by line in same direction inside the area. Please check if the area looks wet with the liquid.

2. Wipe off

Pika Pika Rain’s microfiber cloth

We adapt finely woven microfiber cloth to work well with the liquid. Microfiber cloth never give damage to glass coating nor paint surface. Please wash your car always with microfiber cloth and whipped car shampoo.

Tricks and tips for wiping

Soon after you apply the liquid, wipe the area evenly and quickly in a listless way. You don’t need to wait. Without folding a microfiber cloth tightly, just move lightly the microfiber cloth to catch the liquid on surface.

3. Check

After wiping, please check the car from various angle to find the foggy or uneven surface. When you may find the unevenness parts like finger print, wipe them again. When you find the unevenness after curing in 12 hours, it’s quite hard to remove. Please check twice. In case that you find the unevenness which you cannot wipe off, just try to put a drop of liquid with sponge, then wipe off again. This may have effect if the surface is not cured completely yet.

4. Curing

Please be careful not to get wet during 12 hours: surface curing.

Water sometimes drops around side mirrors, or gaps between doors. If water runs over the coating, it might be cured unevenly. Please check the car in a few hours after application. We also recommend to work in the morning to prevent frost and night dew especially in winter.

2 weeks in complete curing

After surface curing in 12 hours to 2 weeks after, you can drive the car and you can get the car wet. Just only the surface cured and it’s in sensitive condition. Please wipe the surface very gently if it rains or if you wash the car. Please don’t make water stay on the surface.

After 2 weeks, you can apply Nano Pika Pika Rain quick detailing spray for better condition in gloss and water repellency.

  • Do not allow your car get wet for 12 hours after application.
  • Do not use Pika Pika Rain glass coating on glass surface or tires.
  • Do not re-use the sponges or the cloths.
  • It takes 2 weeks for full hardening of the coating. Do not use a car-wash machine during this period. (Washing by hand, using a soft microfiber cloth is recommended to avoid scratches from car wash even after 2 weeks of application.)

How to double coating /
2 layers coating of Pika Pika Rain

Pika Pika Rain’s glass coating spreads very smoothly and thinly, and you can feel it if you compare with other glass coating products. Though it depends on the model of the car, you just need 2-3 drops for 1/3 of the hood. So, some customers still have half of the liquid after finishing the application. We receive many phone calls to ask if they should do “double coating” from them.

Of course, YES. Please try!

However, we would like to tell you what you have to be careful about.

1. Set a schedule

Second application should be done in 2 weeks ~1 month after the first application as the first layer has to be completed.

2. Store the bottle appropriately

If you will plan to use Pika Pika Rain liquid leftover in the bottle you have already opened, wipe the mouth of the bottle, then put a cap tightly. Please store the bottle in dark/cool place like fridge.

Before the second application, confirm if there is NOT crystalized liquid or white power on the mouth of the bottle. When you find that, please stop reusing the liquid to prevent scratch on the first coating. Also when you find the liquid cloudy, please stop the application.

3. Second application

How to work is the same as first application. Please use new microfiber cloth and application sponge. You will see deep gloss and tough glass coating over the car in further 2 weeks!

Can we apply glass coating to brand new car?

Would you like to cover your brand new car with Pika Pika Rain glass coating? When you handle brand new car, there are some points to remember for you before starting application!

1. Confirmation with auto dealer

Please ask auto dealer NOT to wax or coat your car before the delivery

Auto dealers sometimes do waxing / polymer coating to hide small scratches or to make the car look better before they deliver the car even if you don’t ask for that. In that case, as Pika Pika Rain glass coating has to be made over clear coat without wax / polymer coating, you will need to remove wax or coating. Please ask them not to wax or coat the car in advance. We also recommend to ask them not to use car shampoo with water repellent effect.

※Caution: Without removing wax or polymer coating on the surface, glass coating may be removed along with them after daily car wash.

Please ask auto dealer NOT to use car washing machine

Every auto dealers wash your car before the delivery, but there are 2 types of car wash; by hands and by machine. Car washing machine may scratch your car with tiny dusts inside brush. Small scratches may become difficult to see by the reflection after Pika Pika Rain glass coating, however scratches themselves cannot be removed. If they cannot accept to wash the car by hands, please try to ask them to choose high pressure washing machine without brush.

2. Attentions for car owner

Wash your car even if it looks beautiful

Many customers think the application can be started without washing the car when it7s really brand new soon after the delivery. However, tiny invisible dusts are always over the car. Please wash the car before Pika Pika Rain glass coating.

If you are not available to use car shampoo at that time, it’s ok only by clean water. Please make sure to wash away something on the surface. If you apply Pika Pika Rain glass coating liquid without car washing, glass layer may keep in the dusts inside. (In fact, some customers did that.)
