Grayguns can arrange for any of the excellent finishes offered by Cummings Custom Refinishing (CCR) including Ceraplate (Nickel Boron- Corrosion resistant but harder and more durable than regular nickel through the addition of Boron, great for steel frames and slides) and any of the Cera-Hide ceramic coatings (great for alloy frames and carbon or stainless slides/frames). Action work should be completed before any finish is applied to the gun or parts.
When arranging finishing with CCR or other vendors there is a minimum $60 charge to cover our time with metal prep (stripping of original finish, bead blasting and light dehorning as necessary) and the cost of shipping with insurance to the vendor. Payment for the actual finish is supplied by the customer directly to the vendor. The parts would then be returned to us for assembly and final testing/sight regulation.
