I've done quite a few of them.  I dismantle them, and solvent clean them.
I've had them powder coated seni-flat black at this point, and I've also
painted them with semi-flat from a spray can.  I use a small file to touch
up any nicks, and lightly sand with 600 grit sandpaper prior to painting.  I
generally service the locks and then re-assemble.
