Ha, not a bike but a helmet I picked up last weekend at a swap meet. I found a beautiful red sparkle, not for riding vintage helmet (show-off purposes only) and when I got it home began to remove the liner to redo all the vintage skank inside. I thought I looked it over pretty well but under artificial light I noticed a crap load of cracks. Has anyone ever dealt with this? Can I buff them out or do I need to sand the helmet down, re-glass it and repaint? I hate that I didn't see this until after I started working on it but it's too gorgeous to not try. I'm fairly certain that I probably did the majority of them flexing it to get the styrofoam liner out although I was very careful. Anyone have experience with this?
