Im really confused at what your saying here? What makes you think UFF doesnt have to be hand washed? Its not going to stop an automatic car wash from marring the finish. And what coating do you think costs $1000 and only gives you 2 years protection? Any pro level coating is going to last at least 10 years. Its the consumer level coatings that last 2-5 years but they only cost around $100 for the product.
Referring to the second half of your questions he was referring to my statement that I paid around 1k for my opti-pro+ 2years ago and when I traded it this month the front end looked like it had been splattered with white paint because of all the rock chips. As far as shine, discoloration, ability to clean, etc all of that was perfect still. But as I said in that post nothing protects against rock chips, the closest is any kind of self healing film.
