This may be a dumb question, but I am cleaning the underside of my bird and am stripping the thick tar under the wheel wells. My question - Is this factory tar for "rust proofing" or road tar that I should strip off as part of the restoration? The more I pull off, the more it seems this might be a good protective coat to leave on....
If it is meant to be there, how do I clean it up or restore it? It comes off ok with heat gun though definitely a slow process. If it needs to come off, is there a better way?
