I ride a trek touring bike from the early 80s and it has some rust spots and other cosmetic issues. Three questions in one:


1. I am planning to retouch it this weekend using nail polish or auto paint. Should I remove the rust from the spots before touching up the paint? If so, how do I go about doing that?


2. The frame has some white paint on it that has rubbed off from other places (fences, doors, etc). How can I remove this white paint? Will paint thinner mess up the frame or paint job?


3. Also, I would like to clean up my headbadge if possible, which is covered in soot and grime. It looks like this:

except is it dirty and black and unreadable.

Anyone know a method to clean up the headbadge?
