I used to be a big fixed gear cyclist, but I've recently hit hard times and am currently fighting out of homelessness. I just got this huffy mountain bike (don't laugh, use to be that I wouldn't be caught dead on a huffy, or any mountain bike) but it's what I've got right now for transportation and enjoyment of cycling. I got it ans there are some places on the frame that the paint has been scratched off, it's been stored indoors so there's no rust or anything but i will have to store it outdoors for now and im trying to figure out the best (and cheapest) way to protect those spots. I'm not gonna have this forever just for now until I can afford another trac bike.does anyone have any ideas how to protect those places?
