I see you live in Phoenix. I suggest you give Tim at www.acoating.com
in Peoria a call. He did my P-6 and it looks new, he also did a silver color Ceracoat on my P228 and we kept the slide Deep Black. He does great work and is very reasonable. His company is called Alternative Firearm Coatings, he does gunsmithing also. Good luck with whatever you decide to do. I discovered him in the Phoenix Back Page ad. Lucky me.
