... The first video shows the film being scratched up with a brass wire brush. Next the tech pours hot water on the film and ALL SCRATCHES ARE GONE!! HEALED!! The second video depicts Self Healing (i.e. no water ) Same brass brush treatment no water just a clock in the background. THE DAMN FILM HEALS ITSELF BEFORE YOUR EYES!!! I cancelled solar guard and 3m samples immediately.
That's pretty cool, for sure

Still, the 3M "clear bra" plastic is evolved from a protective film for helicopter blades, which has gone through some quite tough time-testing. I don't know how this new stuff stands up over long periods (years) with UV sunlight, etc.
We'll know in a decade which one is (or was) the better product
