I just picked up an old '88 Sportster 1200 as a first bike. With the help of a couple dudes, I got it running good. It rides and sounds good, but it's nothing to look at. I've spent a few hours with fine steel wool and WD40 to take off a lot of the rust but there's still some left on it. Any other tips on how to remove rust would be appreciated. Also, if anyone has ever rattle canned their bike, does it matter what kind of spray paint to use or just anything that's around? I got some touching up to do on the frame and wouldn't mind blacking out some of my covers.
