I took the front seats out did that entire area didn't do from the rear seat back as paint is still good. Don't see how it could effect anything. I used the rustoleum brush on kind. I know alot of guys use the rattle can but I didn't want spray everywhere. I will also post about how it holds up after a few months as I am ruff on my interior. Also might paint it depending on how hot the black gets as I don't have carpet and im barefoot all summer.
