The rolls were wound so tight that the vinyl separated from the backing in a line every few inches. I laid each roll out flat on the countertop overnight but still so much curl and paper separation made it very hard to handle. I tried both dry and wet application but neither worked very well. Probably should have laid it out in the sun before I unrolled it. Bad experience! USPS beat the heck out of the box, not to mention getting it wet during the 6 days it was anyone's guess where it was. Tracking said expected delivery Friday. Got it Tuesday. Par for them tho. Contents was sealed well and undamaged. Just thought it should be easier to work with considering I removed all the trim from the vehicle first. Live & learn!
