Leave it to the Russians to test it with a "gun". lol Nice find on the chart.
I have the 3M film on my 135i now for almost six years. It really has held up well. When you hit bug at high autobahn speeds... its like a small caliber gun. I'm really glad I went with BMW's clear bra film(kit) on my car.
