The Metalizer i posted about is a wonderful way to restore a pitted Firearm .
The shop i know of that uses this machine for industrial Pump Parts also gave me some Hydralloy ,.it is similar to Nicklealloy or Chromealloy type Rods in that it has the Flux made onto the rod.
With an Acetylene Torch i didn't have to even get the Metal all that hot , Its a flowing build up process not a welding process.
In other words it builds up surfaces so they can be Milled down to Spec once more. Like the Back Plate on a Mission centrifugal Pump .
The rod i was using was 41/40 steel ,i was eliminating pits on a C96 and i spread the Metal so thin i used Files to shape the Frame up like new.
If you clean the Parts good enough this stuff will just flow into a pit and harden as soon as you move the heat off it.
The Machinist said this is how it has been done for years and it wasn't anything New . Their is even a Bauxite mix that you can use on Aluminum also , but you better be good at Brazing with a Torch to use any of it.
