When I stripped the paint off my car initially, I painted the bare metal it with cheap rattle can primer to keep it from rusting. Now I need to strip off the primer to lay down body filler. The weld-through primer comes right off with brake cleaner, but the red primer (rustoleum or duplicolor) doesn't. I really HATE to go back to the aircraft stripper to get this stuff off after I already stripped the entire car with it before. Any recommendations?
