The dynamat, at $33-39 per linear yard is pretty pricy. Go to Home Depot, Lowes or a big box home center and go to the roofing department for Peel n' Seal (may be another name)... it goes for like $20 for 12 feet. Much cheaper and very effective. use it just like the other stuff. Others have said that even in Texas heat it works fine.
Dan, for storage, add pockets on the front edge of your seat....
