That stinger stuff is listed as 1/4 inch carpeted material. Much different from the typical hushmat or dynamat you normally see. Dynamat does make a carpet mat like this one for double the price. Their website also shows the peel and stick type as well. Would liek to hear some reviews on it. I have two cars to do. After driving Mike Tylers car that had dynamat type material inside I really like the results in a musclecar. Would be nice to get the same results at half the price.
