I am not a frost paint fan at all, it looks unfinished for me, but that's a personal opinion and I hope people who choose it will enjoy it.
However, I have a friend that has one, and I can tell you that a bird shit couldn't be cleaned with anything. After so many tries of different technics the spot looks actually awful. So I will say, No thanks...
Anyway, for me, shine is an element of pride, of a car well mainained.
