GM undercoating on new trucks??
I have seen the GM offers an undercoating procedure on new and used vehicles now. They also offer some type of rust protection for the inner door panels, jambs, etc. Do you guys have an opinion either way on this? Was wondering if it would be beneficial for those of us in the rust belt. Thanks.

Did some more research. Basically on the newer trucks they don't have any undercoat (a tar compound). They have a wax dipped frame, but that's it. GM offers to spray the tar undercoat on; they get the underside of the cab, bed, fenderwells, etc. These areas just have regular paint on them. However, they are supposed to galvanized steel. Now I also heard that the undercoat was not good because it absorbed moisture. Anybody else heard this theory?

Yeah when you use a jack on the frame the next day there may be a little rust from where the tar crap came off.
The galvanized steel is in the body panels. When I had the accident in my truck, and caved in the whole side of the bed. A month went by and the bare metal never rusted, even where the deep gouges were.
