I can see using the peel and seal variety in the doors and lid to prevent oil-canning. Where I become a gutless turd is sticking the stuff all over the floorboards and behind the gas tank. I think my biggest concern is that the next guy to have to do a repair there (me) will have a hell of a time getting it up. Not yet being in that situation I don't know if it will ever be an issue but that is why I can't yet seem to pull the trigger.
Anybody have to re-visit a place where this was stuck down and if so what were the challenges?
