Never heard of clearshield. There are a lot of brands and most of them just put their name on someone elses product (as in the case of armorfend, ventureshield, etc etc etc). Kind of like how most tissue paper is referred to as Kleenex or any cotton swab a qtip. 90% of them are using some form of 3M, including starshield. It used to be the best and everyone knows the name, but quite honestly it's just not the top of the game anymore. There are a lot of variations in quality even from the same manufacture (coated, uncoated, thickness, orange peel, porousity, strength, clarity, etc). I've got samples of almost every franchise product and firmly believe the product I use is the best I've ever found from anywhere, and I've compared and tested many of them. The whole front of my car is covered and you can't even see the stuff. On the way to LOG I hit a chunk of tire rubber that was bouncing down the road and left a huge black scuff. A bit of Zaino all in one later and it was totally gone with no damage to the film. I put a sign in my window at car shows when parked because otherwise you would not know there is film on the car (when it's more than 50% covered in film) and people come up to me asking me what on the car is covered because they can't tell where it is.K - Not to be dense but I'm not clear on what you're using ...is it clearshield or something else?
