I dont think it'll rust that badly sitting in your garage as is. Im generally a fan of restored, but when I do patina, I typically apply a matte clear coat if I dont know where it's going so rust wont shed off on peoples living room carpet. O'reilly Auto Parts sells some really easy matte lacquer clear, about $40 a quart, no mixing required but sprayed with a gun, dries super fast. It also mildly enhances the contrast between rust and not rust areas, looks better IMO.
