I purchased my RV in April 2015 and thought that the Windows just needed cleaning. Wrong ! They were fogged. I read everything I could find on this forum about fogged Windows and decided to order the supplies from Amazon. Once the supplies arrived the project began. The first was the hardest with each one thereafter much easier. I have them all done except the slide side bedroom windows but may do them this year some time. Just be patience and enjoy the work and they will look better than new. I also saved a lot of money. I think my cost was about $200 and I still have enough supplies to finish my last two windows. Contact me if you would like more specifics. All work was ONLY accomplished because of the info provided from folks on this forum.
