In my not so humble opinion, it's the strongest finish out there. A buddy of mine used to have an SRP in Bearcoat, carried it DAILY for 2 years and saw NO WEAR. Doesn't get much better than that! Plus, it's made by DuPont, so the same basic formula is used for the finish on a lot of cars and even some equiptment sent into space by NASA. Durable enough for you?
