I have a fender bronco. The little tweed amp.I live down hear in Florida, right on the ocean. The air. is very corrosive to metal.. Well on our back enclosed porch,I left it out there for only a few days. All the metal is rusted. Surface rust. To clean it up, I will destroy all the lettering on the chassis.Can I get a replacement chassis?I was also thinking about ,Converting it to a small tube amp. I see those kits advertised. 5f1 ,I think they are. Is there a way to clean up this chassis, Can I get a silk screen done to the cleaned up chassis? Or try to convert to a small tube amp? thanks.
