Like I said earlier, be sure to use a lot of heat. It all depends on what you are doing with it. For my mirrors, I took them off. Then had a friend help me hold the other end of the sheet. We held it over his stove to get it pliable and then just pulled it down over the piece.
For the parts that get wrinkled, just pull it back up, use a heat gun to get it workable, and then just repeat the first step by pulling it down. The material will get really loose when held around heat. You will see when you do it. Also the stuff I ordered off Ebay has a 4 year warranty and has the texture in it. It showed up for me the next day with free shipping.
Good luck!
