This 3M Door Edge Protection Film contains two strips of virtually invisible clear thin and strong Edge Paint Protection Films which has adhesive on one side and clear plastic on the other. The Adhesive helps to stick on the car's door edges and stay put if applied properly and thereby protecting the paint surface from accidental scratches or dings.From my observation using this product it was clear that the material is not thick enough to take serious abuse of the door against unwanted bumps into other objects. This was clearly intended as sort of "peace of mind" for people who love and care for their "new" car and are extremely conscious about slightest dings and scratches on their shiny newly purchased car.I know, I know I have gone thru' this before when I had bought my car years ago even a single scratch or even a bird droppings on the windshield would make me upset. This product is for people who would like to protect their investment from possible daily bumps and accidental scratches to their car's door edges.Applying the product does require high degree of dexterity. It can be complex if your car has multiple bends and curves. But with patience and a steady hand most users of the product can apply the clear tape with relative ease.Just make sure that the surface of the car is clean of grease and is dry before applying. It is intended to be a permanent solution. So after applying if you want to peel the Film be prepared for some surprises like glue sticking to your door etc;The product itself is "3 star" [It is OK] worth. But the price factor pulls one star out of the 4 star rating [I like it]. I think it is worth half the price that is being currently offered. If 3M included 4 strips for 10 dollars it would be a 4 star product.But hey! if you love your car and care about not getting scratched or paint chipped off your door, you will pay anything for it right? - May be.. May be not...! depending on what type of car you have and what is the current condition of the car.This Protection film might have other uses too.. basically any metallic shiny painted surface which needs protection can benefit from this industrial grade clear tape.
