Plastic very thin, wrinkles returned, but it worked.....
The plastic is much thinner than the product I used in the past (not sure if Duck Brand) which made it more difficult to install by myself so a friend helped me. After installation, I used the hair blow dryer to remove the wrinkles which it did; however, the wrinkles returned overnight. I could try the blow dryer again but I still have a clear view out the window so I won't bother.
