Recently sent a new S&W 629-2 mountain gun, a Marlin 1895 LTD V, Browning 325 A-Bolt Medallioin and a Springfield 1911 TRP to have a complete Robar / NP3 treatment done on all four guns.

Anything I need to tell them, to do? I know they completley take the guns apart, do the treatment and re-assemble, and I'm happy with the guns as modified, where applicable.
