Yes, I sanded and repainted mine years ago and it still looks good. There are many threads about how to go about doing it on the forums.
General steps are....
Clean
Mask the area off
Sand, multiple steps with different grit paper.
Prime, 2 or more coats to fill in the pits
Sand between coats of primer
Then top coat, Trim black found at any auto parts store, maybe 2 or more to your liking.
Sand between coats.
Remove masking
Enjoy the new look.
