Glass coating pika pika rain that is the most popular in Japan

Mr. M.H / Saitama, Japan / TOYOTA HARRIER 2016model

I applied Pika Pika PREMIUM Ceramic Coating on the fine day of January.

I did the following works as preparation.

washing → removing iron fillings → car washing again → removing oil

Then I did the first application, but half of a bottle remained,

so I reapplied it again 2 weeks later.

It took about 4 hours which from car washing to the first application.

When I splashed the water to the car body before the first application, the water didn’t leave on the car body,

but after that, the water repellency was so nice like the water was sliding smoothly.

I felt not only the water-sliding repellency but also the gloss was much better than a brand new car.

Now, 3 months has passed since I applied it, but the gloss still last.

The water-sliding effect was getting weaker here and there even though I washed my car once two weeks,

but I’m satisfied with the gloss, so I’m going to Nano Pika Pika Rain Type-K, too.

I hope their improvement regard as the durability in the future.

Please tell me how to get the water repellency again!

(From staffs: You should better to use Nano Pika Pika Rain Type-K!)

I don’t want to test on my car because I applied it with much effort,

but I want to know the difference between washing by hand and car wash machine.

(Because I feel tied for washing by everytimes…)
