Purchasing a new 5th wheel and paint protection

Don't do it!! I had it done and 2 years later when I had it into the dealership for a repair I mentioned that the cap looked faded. They had a guy come out from the body dept. to look at it. He said it should have been waxed twice a year. When I told him I was told I wouldn't have to wax for 5 years he just rolled his eyes.

Long story short I got them to fix the cap, but the dealership body dept. said no coatings will take the place of waxing. I feel the money we spent was a waste.
