you dont have to poly fill it, but you can.....i think it is .75 lbs per cubic foot.
as for the deadener........make sure the cans are room tempature if thay are cold they dont spray good........let them sit in warm water if they are cold

I sprayed my glass box with 2 bottles of Wal-Mart truck bed liner and it worked great.

those name-brand sound deadner sprays are expensive, and ive found over the years that regular rubberized undercoat spray is way cheaper, like $10.00 cheaper a can (you can get it for like $3.00 a can at an auto parts store) and the cheap undercoat sprays about 100 times better. audiomechanic is right about the temperature thing.
