Just get them painted, or try plastidipping them yourself. Some people have even used vinyl wrap.
No, no texture. They are pretty smooth. A coat of paint and clear coat would make it really smooth. But I'm planning to plastidip mine, that way if I don't like it, the plastidip will peel right off.Don't they have a rough texture to them? I feel like body panels are normally smooth and that would change how paint looks on them.
