ALL,
You know what I thought was weird one time was when I saw a friend of mine after washing her Jeep Chreokee... she was using Pledge of all things on the plastic fenders of her Jeep. I asked her what she was doing and she explained to me that her dad is a car sales man and one of the tips her dad had taught her was that the pledge had some things in it to keep looking like new... and a couple of days later I was lookin at the fenders and they still looked as if they came right off the dealer lot... mind you the Jeep was/is over 4 years old... and she was gettin it ready to trade in on a Jeep Liberty. Just another suggestion or food for thought... I don't really know how close in material our cladding is too her fenders, but I'd say try it on a small inconspicuos spot on your truck and check it out. I haven't done it yet considering my truck barely has 3000 miles on it.
