no i mean old fashioned cold rust blueingDo you mean cold blueing? Ie you strip the metal of grease then apply blueing agent let sit for approx 10-15min submerge in water/dry and buff with fine steel wool... it works on all gun metal that I have put it on (steel).
Take the metal parts out of the action and strip them to their base parts as best you can then do each part 1 by 1. An air compressor helps to dry. Do not rush treat only the number of parts you can manage to apply blue sit for 10/15 wet/dry/buff. Several coats are usually requires depending how stripped the metal is. It does start to look good after several applications.
I have touched up the blueing on my Norinco JW25a if that steel can retouched anything can.

As in a "damp box" set up?
Post 64 receivers had an alloy in them that did not take bluing well.
