Dynamat / Peal n Seal... yes or no

I found a decent deal on Dynamat from Summit. I was able to do my entire floor with one box. f you get a promotion coupon then you can save a little more. I think I paid $125 3 years ago.

Sounds like there are some good alternatives out there for less $$$. I may put the other stuff inside my doors.

I did use the bubble foil from Lowe's for the firewall. Really easy to copy/trace the old fiberglass padding and the plastic OEM plugs still work too :)
