Total Blackout Film - All White

Easy to use! The gridlines on the back help with cutting a straight line. The sheet is thicker than i expected. Followed the directions exactly (6 drops of soap!) worked well. It was easy to get the product in the window smoothly and it does a great job blocking the light.

Purchased 1st roll from Amazon, liked product so I bought 2 more rolls for a slider door directly from Window Whirl. Unfortunately one of those rolls came with a stain. Thought I could remove it, but I couldn't. Will send pictures if you want to see the stains.

Works perfectly.

It did make difference in blocking the sun in a small arched window that I was unable to get a shade to fit.
