I think I screwed up

[sjarrett71]

I got a set of Dashtop door panels. The original color was black but were painted blue before I got them. I tried to paint one black but it came out really crappy. Part of the paint looks like velvet and has a grainy texture to it. It was really hot outside and there was high humidity. Do you guys think it would hurt the plastic to use a paint remover or diluted thinner to clean both layers of paint off so they will be black again?
