Shoddy Pad Insulation Alternative

I used DynaMat products to do the inside of my Dart, but didn't want to use the self adhesive stuff on the floor and firewall in case I needed to weld there in the future so I bought the thick DynaPad material (non-adhesive) and glued it to the cardboard pieces that the factory used and used the original factory push in plastic pieces to hold it in place. you can cut the dynapad to actually fit better than the factory pieces. I ran the DynaPad all the way down the firewall and under the carpet and removed the padding that was glued to the carpet. It does not absorb and hold moisture.
