I was told by a shop that sprays bedliner that if it's a hot application type of coating (some are cold spray, some are hot), then you can't spray over that tar insulation. It'll heat it up and the spray will react with it, and probably won't stick.

I'm not looking forward to removing that crap when the time comes.
