for most grand owners myself included krylon fusion is the best product to get your cladding black and have it stay that way. it is also smooth unlike bed liner and really easy to use very little prep needed. I did mine over 3 years ago and it still looks great only a few light spots where car doors and branches have really hit hard. I have seen that it now comes in a wide verity of colors even hammered finish. here is a pic at about 2 yearsafter paint, I used black Im sure you can find lots of threads if you do a search for it.
