Best paint for steel AR mags

[howie]

Went out with the fam yesterday to do a little plinking. Noticed some rust on a couple steel AR mags. Wondering what the best paint is to redo them with...

I have plenty of friends that rattle can their shotguns and AR's. It holds up well enough and is easy to re-apply.

I have been using Dura Coat and find it hardens to a tough finish.
Brownells Aluma Hyde also provides a tough finish.
