I bought some McKee's 37 ceramic pain coating to try out on my and wifes cars. Hers is a 2016 fusion with the tri coat paint. The paint is in pretty good shape aside from a few scratches that im not to worried about. My cobra on the other hand has paint that is several years old and while it is in relatively good shape it is not without its issues. There are several spots with rids that im pretty sure will not come out and it has its fare share of rock chips on the front end/hood. The hood is probably the worst. I know ceramic is supposed to have as good of a finish as possible to adhere too but am I wasting my time if its not 100%. Will the coating fail or will the scratches just be visible for as long as the coating lasts?
