By accident I ran across this stuff at Lowes its called Peel and seal self stick alum roll roofing it comes in a 100 sq. ft roll for 79.99 36" by 33' long according to the box it comes in smaller widths. I used this weekend to do my 87 dually. works great easy to use. I didnt even use a heat gun but its pretty warm here you might have to use the heat in colder climates. I dont think I used even 1/2 the roll I may do a second layer. Just thought I would pass it along.
