Dynamatt is still king in my opinion. In my last install I put it up against the hype of Peel n Seal from hardware store being just as good. Its not. Dynamatt much thicker so more effective and zero odor. Peel n seal will not smell as long as its used in a way that all adhesive bitumen is making full contact. If its used to cover door openings as in sealing, it will smell. Dynamatt is expensive but buying from this site is about 40percent cheaper than Worst Buy. I feel its worth the expense.
