It's not only it changing color it's also they fall off. The actual piece that holds it to the good stays on but the emblem falls off. Maybe I got a bad one I don't know but I do regret getting them and I don't want to bad mouth the product because I was happy for a month and they looked sweet. Now I can't even tell if their CF.
As for bimmian yeah their overlay but vinly ones and they have held up beautifully. Anyways I'll pm you. Maybe clear coating them solves all this
