Removing Exterior Film

Hey guys, We have a large exterior film removal job soon. Tested a window and it's not gonna be fun. Steamer was worthless, seems the film is too thick for it? Didn't try to sweat it yet though. Think it will work? Ammonia, Simple Pink? Thanks Fellas!

simple pink hasnt failed me yet. Make sure you where chemical resistant gloves though, especially if you use it full strength. A mask mak help too if its windy. Let it sit on the film for about 5-10 minutes before scraping. Get the stiffer scraper blades as well.

Do you know what type of film you will be removing?

Thanks CE. I have no idea what brand it is. I do know it has been on for about 8-9 years. I might have underbid this removal!
