Duracoat for pitting
I posted a variation of this question on the FirearmsTalk section of this site inquiring about nickle to build up a pitted receiver surface receiving responses dubious of it working. Was reading about duracoat last night and wondered if a pitted surface could be wire brushed of rust and filled with this finish to cover pits? If I should just forget about this topic, let me know and I'll drop it.

Durocoat is a paint.
When using it, I always apply thin coats like directions state.
It will not fill the pits unless you spray it, sand it, spray it, sand it, spray it, sand it........

Depending on how deep the pits are, structure integrity may be compromised and paint will not stand up to the duty.
Another thought if the pitting is not deep is to use J-B weld (sparingly) as filler, sand smooth, then durocoat.

What you can do is get some JB weld or other metal epoxy clean and degrease the firearm. Mix up the epoxy and apply it to the pitted area then sand it down to the same level as the metal then prep and spray with duracoat per instructions.

Great minds think alike!

Thanks for the replies. I suppose the "molten nickle" treatment followed by a black nickle as my original post in the other forum suggested would not be a recogized restoration treatment? On another board someone suggested tig welding and again, I don't know the extent of the pits or if that would be what a restoration specialist would do and follow with a more traditional bluing process?

Nickel is not applied in a molten state. It is transferred to the metal on a molecular basis. If the gun you want refinished is to be nickel plated, pits can sometimes be filled with lead-free solder and sanded smooth. Then the piece can be plated with electroless nickel.
If the gun is to be blued, welding is the only option.
Painting it is the easiest method.

If you epoxy the pits use a sanding block when sanding so you don't remove too much to it.
