I sanded the body down to metal.. slowly over a few days. I only found the one other bit of rust that wasn't bubbling through already. I felt quite relieved! I'm disabled, btw, so these photos are over the last year or so when I feel like I can do a couple hours worth of work. I just hit the body with a single coat of Rustoleum paint n primer in one to keep it from rusting until I get it to a paint shop. I'm trying to do as much as I can to save money... I'm just livin on VA disablity, so...
