Re: Firewall Sealant Mystery Stuff
3M Rubberized Spray undercoating (aerosol can) does a reasonably good job of mimicking that look.

Re: Firewall Sealant Mystery Stuff
Found a can still in the shop. It says "3M Professional Grade Rubberized Undercoating" . The part # is 03584. I admit I have not bought any in some time and have not verified its current availability. It sprays on pretty thin and dries to a flat sheen.

Re: Firewall Sealant Mystery Stuff
I used Evercoat #101348 rubberized undercoating to duplicate that factory sealer on the firewall of Dad's 77. I've found that the Evercoat brand undercoating seems to go on a little thicker than the 3M brand. But neither one of them is quite as thick as the factory stuff.
