I used this mud to patch up around the copper AC lines(pipes) in the brick wall, excellent material, soft enough not to damage the copper pipes which constantly vibrates(even it is at micro levels) when AC/furnace works, and thick good enough to block heat/cold leaks and blocks insects/animals access to the inside of the house.

Great stuff, nothing bad to say

The Duct Seal was exactly like I anticipated—like a heavier thicker putty of dense cookie dough. I used nitrile gloves and that prevented the putty from sticking to my hands and it is very tacky to the touch. I tore it off in enough lengths to fill the gaps around my boiler exhaust flue. Used the whole 1lb package. No complaints.
