You should call Chevy Duty and ask them how to unroll it. If it were mine, I would spray it very lightly with some water, wait about 15mins or so, untill the cardboard becomes a little more flexible. Then try to flatten it out on a table with some objects holding it down till it drys out again. That is if it were mind. I don't care as much if I screw up something of mine, but I don't want someone to take my word and screw up something of theirs because of my say so. Do at your own risk. Cecil.......
