Peel & Seal is the way to go. I've used both, DynaMat and Peel & Seal and can tell you first hand, Peel & Seal is about 1/5 of the cost, you get enough to do the entire floor of two cars. I POR15 my floor first, then Peel & Seal. Killer combo that knocks out the road noise, droning and heat. Comes in a box 36"x50' for less than $100! Can not go wrong!
