Don't have any pics, but I painted mine with a foam brush(es) and gloss black rustoleum in the can. Holding up fine, other then the door bars where it is scuffed from me getting in and out.

Make sure you have REALLY good lighting though if you do it this way...that way you can see if you laid it on too thick or missed any spots.

If I had to do it again, I would have painted all the bars FIRST with a spray bomb, done the welding, and then touch up the areas with a brush (I installed my own cage so this what I found in hindsight would work and look best)
