Yep, that's the stuff.

I believe it was reformulated due to environmental and durability (it's pretty soft once dry) concerns. Unfortunately the replacement is not as "dead" as the original. I bought up several cans for future use before it changed. I read somewhere that the original formula is/was used by amateur telescope makers to coat the insides of their tubes.
