bcb is correct in this product it is put on at the factory on high end cars for rock chip protection. it can be put on fenders and the underside of the nose of the boat so in tow you get no rock chips. it is really a very good product.most of the window tinters here where i live install the stuff it is kind of expensive but is well worth the money and you can not see it unless you are right up close. alot of the guys here use it
