Windshield is almost impossible to see out of.

I have used this cover on a couple of different golf carts and it flexible enough to use. One cart it was a little tight and on another brand it was a little loose. The issue I have is the front windshield. Mine is almost impossible to see out of. I deffinately can not make out a golf ball on the ground. Currently I have to drive with th side window open and look out the side of the cart. I have tried using a heat gun as mentioned in one of the posts to get the wrinkles out and I have had it laying flat on a surface for over a week but so far no luck in improving the vision.
