So they are looking to use whiteout.
I've gotten a yes... it's a ps film and will be ok ontop of the factory frost, and a no... it will act along the same lines as when you put tint over the matrix on a car.
Has anyone ever done this before???
It's not super rough... the surface... but more then smooth glass. Hmm... I have a glass top desk which is frosted on the underside.... it's not as smooth as that, but along the same lines.
Yes? No? Maybe so?
