Roofing tar? Really? What an interesting idea. I mean, it's meant to prevent water from penetrating on a roof, so why not? It would be tough to mentally prepare myself to take roofing tar to a neat old survivor truck... a mental hurdle that probably doesn't even exist to a motivated 18 year old.
Gotta be tons cheaper than any automotive specialty product that tries to do the same thing, too!
Roofing tar and used motor oil. Huh.
