Ok thanksYou mean is very flexible and won't become hard and brittle and lessen the chance of rock chips?
It may have less scratch resistance, but you can buff it down the road and make it like new again.
It's been used by many top restoration shops for the last 15+ years, durability is not an issue with the Universal.
Actually I find it more resistant to scratches because it has more flexibility, it almost seems to heel itself with minor scrubs.
