Pretty outcome. I took one star from the fact that my husband being very patient, witty and a perfectionist, he worked out every air bubble and the film not sticking on his own, he squeezed all the boards into the window joints so that it won’t lift overtime. 
Another star taken is because it’s more see through than expected both from the inside and the outside.
Nonetheless this picture was taken  on a cloudy day and the rainbow effect is still visible and purdy
