Yeah, I suppose they sand blast them, throw some zinc coating on it and re-sell if they're not leaking.

I think this will be a very likely leaking spot if I don't even the pits out somehow; grind, paint or filler. It's the mounting hole for the check valve. The inside looks better, though, so it might be ok. I'll fix it nevertheless.

I have similar issues there with mine. I plan to sand it smooth with a dual action auto body sander to smooth out and lessen the pitting before taking it for powdercoating. Or even using the appliance paint Mr halifaxhops mentioned. The powdercoat will fill smaller imperfections, either way, a new soft rubber grommet for the check valve should seal pretty well.
