I too buy from electrical supply house. The stuff also makes a perfect
backstop for air-pistol. Comes in one pound blocks. Great stuff.

Must agree, Duct seal or DUX seal (been a few
years) try Greybar, W.W. Grainger, and other
parts houses- think couple ##s cost around $5-10
and probably last an individual a lifetime
(or take excess to next swap meet, and probably
sell it for about what you paid for it!)

the standard stuff for that sort of work around here in the electrical
