Rockets are NOT cheap!! Just rented them....Had to give them back

The foam I used on this one is Roof underlay. 4 x 8 sheets, 1 1/2" thick. Two layers thick with a fiber reinforced paper on each each side and separating the two layers. one layer is 1/2" and very hard the other is 1" and softer. The paper is not waterproof but has held up well on stuff that has sat out for years. I just painted it with two nice coats of oil based enamel and it has held up better than I could have hoped.
