I used to do Glass coating on my previous car, VW Golf, it's good in the beginning but after 6 months, it seems that it has faded away. I am a frequent NS highway traveler to KL and had lots of bugs spatters. This is the first time i am using Ceramic Pro 9h and so far it has worked very well. I do not wash my car in the kiosk so ill only bring it back for washing once every month. The car has always given the extra shine after washing. The best investment for your car if you are very particular on the detailing. Good job!!
