well since paint won't exist in the game, instead RGB colors and textures it's hard to understand you.
have you ever play need for speed carbon or pro street. i'm sure other games have the same paint and decal system as those games but, those are my examples of what i think the SR3 paint and decals should have.
i certainly would like to see a paint and decal system that lets you pretty muhc do what ever you want, including importing your own texture and decal image files.
As far as i can figure every thing else is fair game, even a cock and balls with ricer graphics.
i don't know of any way to censor the user created skins/decals, other than booting them from the server/game.
