My cousin and i found an old (i mean old) road bike in the dumping area of my grandmas apartment. We're going to fix it up this summer and hopefully it will be in riding condition this fall. Most of the parts will have to be replaced cause they're rusting and the frame needs a new coat of paint. One problem though. A lot of the bolts are frozen. How do i get them out? I've tried WD-40 (which claimes it unfreezes bolts) but it didn't work. Any suggestions?
