I'm picking up a 1974 BMW 2002 that's mechanically excellent, interior is superb, body is straight, paint is faded to fuck and back. I'm not gonna paint it right away, so what would you guys recommend to even attempt to restore some sort of shine to this 31 year old paint? It doesn't have to be eat-off-it shiny like my truck, I just want it to look "better". I have the good 6" PC and a full set of cutting/polishing/buffing pads. What's the best stuff I can get over-the-counter to give this paint some sort of credibility while I save up to spray it? Thanks in advance.
