6. I hadn't been under the car for many years, and I was afraid. It was a mess under there, but at least the many leaking fluids slowed the rust. As a bonus there were broken brake lines, frozen drum-brake assemblies, rotten exhaust parts, and a set of coilover shocks--not the cool race car ones, but the trailer-towing kind. After hours of scraping and wire brushing, the crusty floorpan and framerails were metal-prepped and coated with POR-15, which looks much better and should ensure that the rust doesn't return. The axle was cleaned, drained, and filled with fresh lube and the drum brakes were rebuilt before the housing was sprayed with VHT epoxy paint in semi-flat black.
