You'll excuse me if I don't believe you. Either you put the Dynamat Xtreme on top of Peel & Seal, you're lying or you are the first person in 4 years of following this stuff who has bought Dynamat Xtreme that was made out of asphalt. In any case, it should be obvious to everyone who has read this that you endorse Peel & Seal because in your view it is the same crap as Dynamat Xtreme. All that means is that you are encouraging people to use what you yourself have identified as crap. I doubt anybody will be foolish enough to listen to advice like that. Remind me never to ask you for a recommendation for a restaurant.
