What have people used for undercoating their cars? Is undercoating a necessity
or is it optional? The car will be used for occasional street/AX/DE driving. Should I strip the old undercoating from my wheel wells? It looks pretty stable. So far I have cleaned the underside and painted with eastwood silver rust encapsulator. Thanks for any advice. John |

I am in the process of stripping (sandblasting) my car to the bones and I think it must have won the "Let's see who can slather the most seamsealer into das Porsche?" contest at the factory. As I sand blast and dig out kilograms of seamsealer I am noticing rust especially on the bottom seams of the car where seam sealer has sealed in water and in area where the stuff is gobbed on under the wheel wells, especially the fender seams. My thought is that teeners collect water through open windows, leaking windscreens and worn out top seals. That water runs down hill and would leave the car in many instances except that goes through the metal seam only to be stopped by the externally applied seam sealer and is trapped in the vehicle. I'm thinking of primering all surfaces I can reach with epoxy primer then spray on bedliner on the inside floor of the trunks, floor of passenger compartment, gas tank compartment, and inside of the wheel arches in continuous panals so there is no edge for water to get under. I am also thinking of placing some self draining rubber valves (those soft thin wall floppy kind) in areas like the trunk or under the seats to help water exit. Basically as they say in the construction business I'm trying to think like a raindrop. Thought anyone????????????????????????????
