underbody insulation spray...?

[P@@RB@Y]

I want to strip the old tar from the underbody of my car.(Gas tank,frame etc...)

Is there some kind of insulation tar spray thats easlely cleanable I can spray back on?


Thanks

Im planning on using a spray-on bedliner to undercoat most of my 68 Firebird Im restoring. It makes a good protectant/insulator/sound deadener. Also planning on using it on the top side of the floorpans and the trunk. Theres a lot of undercoatings available also.

Spray on materials are messy but they cover up a multitude of sin. If sound deadner is what you want install dyna mat under the carpet on a clean prepped floor. It will also reduce noise and heat
