【Before】
My brand new car has already been applied by glass coating by a car detailers.
I washed it twice in 2 months.
I could find that its hydrophobic was still go on..

【After】
I was going to apply Pika Pika Rain PREMIUM on the glass-like coating by the car detailer (evnen though it was JPY80,000!),
not the best one which was JPY 15,000.

I made up my mind that it was my self-responsibility
that I reapply other coating even though the first coating was still go on.

There is no problem so far, the gloss and better than only the dealer’s coating.
The water repellency changed from hydrophobic to water-sliding.

Now, I want to check the durability on the other coating which I expected the results the best.
