That's about what I had in mind for the outside of the frame. I do have a pressure-feed sandblaster in addition to various wire and stripping wheels. Would you suggest getting the whole thing down to shiny metal, or just the parts with surface rust (the frame under the engine, for instance, is covered in oil and the original paint is intact)? Should I cover in phosphoric acid or anything else prior to putting down primer? How about POR15 under the primer (or anywhere)?
But more importantly: will the epoxy and imron paint hold up as well if they're rolled, not sprayed?
