As I sit in RV parks it often happens that a much more expensive coach parks next to me. A while ago I was sitting at my dinette looking out at the $750,000 (used price) Marathon Prevost conversion sitting next to me and I thought to myself, "What does he have in that that I don't have?"
Well the first thing that crossed my mind is that he could see right in through my windows at me. While I'd never be able to tell if he was looking out. I figured this was something I could fix. I like some privacy and hate being on display.
So I did some reading on the various forums and decided to order two rolls of Gila Mirrored Privacy Window film and an application kit. Then I got busy rewatching the how-to video on Gila's web site and taking notes.

So far it's going well. I've gotten five windows done and I have three to go. I'm not putting any on the windows I use when driving of course. It's not a professional job but it's pretty good, and you only see the flaws if you get really close.
The first picture below shows the bunk windows, which have had the film applied and the side bedroom window which has not.
The second window shows the dinette window with the left half done and the right half not done.
The third picture was taken a little later and shows what it looks like from the inside. The windows over the dinette on the left of the picture have both been coated. The windows over the couch have not.
