I think black looks awesome. however if you do this be prepaired for a nightmare. Most of the time the bolts are so locked from haveing lock tight on them that they will not come loose. You also have to watch out for the innerplate that you screw the bolts into. if it falls inbetween the outer and inner body panels you'll have a hect of a time getting a hold of it.
I wanted to put new hinges on the endgate. I ordered the black kentrol hinges and i absolutely could not get one bolt loose. I stripped out the head, then i had to drill into it, and broke the bit off inside the bolt. I tried an easy out and that also failed. I finally gave up and repainted the stock hinges on the jeep. If something happens that i need to get the endgate off i will probably have to torch it off which will probably ruin the endgate.
Some people have had good success doing this but most have not. Just be prepaired.... one would think it would be an easy job but sometimes it's not.
