Reply to "Undercoating and Rust inhibitors"

I've just finished this process, and what a pain. Is it worth it? Yes it is, however it is possibly one of the dirtiest jobs I have ever encountered working on an automobile. I initially used aircraft stripper to get the majority of the stuff off of the flat surfaces and then used a combination of heat gun/scraper and a wire brush on a 4" angle grinder. Total time to remove all of the undercoating was probably 10 to 15 hours. That includes about an hour to unstick that crap from my shoes, under my fingernails, etc. Just throw your clothes in the garbage. I finished the engine bay with Duplicolor Truck Bed Liner material on the advice of Tom Dupart. I am pleased with the result. Including the body work to remove the major dents and clean up the spot welds and actually spraying the bay, I probably have another 10 hours in the project for a total of 20 to 25 hours.
