I think I have decided to try and go the touch-up route with my Tempo I am stripping down and rebuilding this winter. The paint is in so-so condition. Much of it is nice, but with lots of chips here and there. The brake cable eyelets across the top tube are bleeding rust on the white paint too. I'll try the nail polish route first, but just curious if there are any tricks. Do I need to sand the area first? What about spots that rust is starting to develop, like the eyelets. Any kind of primer down first? And assuming it turns out well, should I try and do something like a clear coat over the whole frame again to protect whats still in nice shape from damage?
