I tried to find the "peel and seal" at home depot and lowes and they had never heard of it. I was able to buy an insulating material that looks like the same thing. I will have to use spray adhesive etc. It came in rows of various lengths and widths and is foil backed on both sides. It is about 1/4 in. thick - used in contruction for insulation so figured it would work. I plan to put it on the floors and under the headliner. Maybe the "peel and seal" hasn't made it to north texas yet!!!!!!!!!! haha
