Anytime you have a frame stippled,serrated, or checkered, it will have to be refinished. In addition to anodizing, Cerakote is an option. I had CGW do the frame on my PCR in Satin Aluminum to create a Bi-Tone look to match my 75B and 97B that I had them get stippled and hard chromed by APW Cogan when those guns were built.
