Are they a bad idea? I recently posted about the National Pinto I found. It is rather rusty in some bits. In particular the top tube. The bike doesn't show any significant structural damage other than the rusty parts. As a matter of fact, if it weren't for the rust, the bike would look like a 7 on a scale of 1 - 10. It's in pretty good shape with shimano parts etc...but thats not the point.
My question is, should I go ahead and bring this home? Maybe get it sandblasted and repainted? I know this doesn't help if you can't see photos, but I promise to head out and take pics of it first thing tomorrow morning.
Anyway, any advice on reviving old, rusty frames would be appreciated.
