I know one of the big deals with my Ram was they didn't LINE the rear wheel wells with anything. With the gravel, rock, mud, and salt over the years, the lips on the inside of the wheel wells became caked with junk, and eventually rusted the wheel wells. I know I have 3/36k warranty and 6/60k on rust through and all, but I'd rather not leave it to warranty to fix this, I'd rather prevent. The thought came to mind of rino-lining the wheel wells, and anything else "exposed." A) is this a good idea B) is anyone with 2006 or such truck experiencing any rust, surface or otherwise on their trucks? If so, post miles on truck as well as approximate area (like NE, or SW, or whatever).
