Calmo2 ;
He's right about posting it in automotive . But to save you some time . I use the foil BEFORE the final two coats of clear .This way it's been polished , the car body is clean and it also locks the foil in place permanently in place at the fiddly corners where it might come loose first .
It's okay to put it on and just coat the foil areas with clear , then polish to your heart's content . I have done it all the ways you can think of and that have been recommended . Tanker - Builder
