I have used both products. The dynamat is the winner. It is denser and thus dampens more sound. The lizzard is nice because you can spray it.
Go to a roofing supply house and buy a roll of Ice Mat. It is cheap per square foot. Is self adhesive. Thinner than dynamat. It does not work as well as dynamat per layer, but it is so cheap you can double or triple the layers and get the similar results.
Ice Mat is harder to find in California, so look for a wholesaler supply.
Thats what I liked about the Lizard, you can spray it, but if it doesn't work as well maybe I should go with the dynamat.
Thanks for the info Mike.
