I installed the smooth Lund fender flares with rivets. Black and MGM doesn't really match together. I plasti dipped mine in anthracite grey, which is the closest color match for MGM, but it is a bit lighter. I used about 1 can for each flare and that is about 6 coats. Then I added 3 coats of glossifier for UV protection. I recently washed my truck using a pressure washer and no damage to the plasti dip.
