1970 Dart Swinger FINALLY UNDERWAY

Surface rust underneath your car immediately after bodywork!? Looks like your car already knows it's going to be receiving Ford parts haha It's playing the part!

Seriously though, don't be discouraged by the light surface rust on the underside. I sanded the entire underside of my car down to metal and used self-etching primer and several coats of black paint. When I checked back under there a year or two later, there was more surface rust showing through. I sanded it down until the discoloration disappeared and applied another coat of rustoleum. I think the only way to keep these old mopars from rusting is to keep them moving! lol
