If you are truly doing a "restoration" project, nothing was polished from the factory.
NOOOOOOOOOOOOOOO.........
Don't paint the aluminum.....it CAN all be polished out to a beautiful shine.
True because most of the aluminum had that clear coat on it right ?
If so however, the only way to make the aluminum look "good" NOW is to sand it down and either polish or paint.
Edit: Well I guess you actually COULD sand all the old nasty clear coat off then put new clear coat back on and that would be a "true" restore.
