I'm going to make a single speed out of my dad's old 1993 rigid steel Giant Iguana. I think its a perfect bike. It looks like many of the bikes I see on this forum, and I've always wanted to try singlespeed. My question is as follows: I'm going to have a friend blast the paint off at his shop and he said he could clear coat it for me. He seems to think this could add alot of weight to the frame, is this true? Is there anywhere i really CANNOT get sand or paint it? I'm goign to stuff the seat tube, BB, and head tube with newspaper or something and tape it off. I think I might like just the paint-less steel look. Do i need to coat it to prevent rust? Do I need to know anything else?
