I have used the ceramic coating and boost on two of my cars and did not have any issues.
I recently applied to a black car. Looked great but once in the bright sun light I noticed a number of areas that were blotched or streaky. I tried to redo with Boost and that just made it worse. It looks like I will have to use a very fine polish and redo the car. Will I have to apply the ceramic spray again?
Also any other suggestions?
