I really like mine, nice shiney finish. I don't haul much so they are still like new. Just 2 or 3 bolts per side (can't remember) and some double stick tape. You do have to drill holes. Only thing mine doesn't wrap around the back which I would prefer but I got em cheap on ebay.
I have a pair of Dee Zee's too and like them. They are clear coated so I never have to polish them either. Mine wrap around unlike wvcat's, I don't know why, there isnt' a seperate part number or anything.
