You would probably have to remove the ball joint and bushings. Pretty sure powder coating is baked on around 400°f. Not sure what that would do to the rubber, but probably wouldn't be to good.

Get a can of rustoleum high performance protective enamel in whatever color you want. Sometimes I use a spray on primer before I brush it on sometimes I don't either way it always bonds for me. I painted my skids, bumper, and sliders in it. It also comes in a rattle can. FJ test said they are aluminum if thats the case you might want to get an aluminum etching primer, but rustoleum also sells a can of that just hard to find sometimes
