home depot: peel & seal. Anything that looks like it is made of rubber/a tar base dense flexible "asphalt" on one side, with fixed aluminum backing. Should also be pre-glued so it is less mess. Make sure it actually isn't asphalt...

Thanx allot!! This helped me allot! So the rubberizing, I just spray it on and that alone will make a huge difference?

I will head to the home depot and get that stuff. will you be able to hear the difference between dynamat and something like this?

THanx for your help! I appreciate it!!
