Is it possible to completely waterproof the cab of an 80's model chevy full size Blazer 4x4. Maybe by stripping everything down to the sheet metal repairing all rust spots and holes then going over every possible seal or opening with silicone then instead of carpet put down some spray down bed liner. These are just some ideas I thought about. But what about the doors? Also what do you think about putting two bilge pumps under the seat to pump any water out the back. Another thing, is it possible to seal all electrical wires in waterproof tubing so as not to short stuff out in water holes. I live in Mississippi, so not many hills to climb but lots of thick mud. ANY advice you have on these thoughts would be greatly appreciated. THANKS Keep up the good work with all the informative articles.
