Want your pistol ceakoted but not sure if you can cerakote your polymer lower?  You can absolutely get a custom cerakote job done on your polymer pistol frame and CTI would be glad to cerakote for you.  Here at CTI we cerakote pistol slides and pistol frames starting at just $60 a piece.  Cerakoting polymer compared to your metal slide is the same process with just shorter times, lower psi, and lower temperature to ensure the safety of your polymer frame and still proper technique. So on the first step of degreasing on a polymer frame we only degrease a polymer frame for about 20 minutes in our tank of mean green compared to metal that can be in there for days.  Then when we sandblast your polymer frame we lower our psi from 90 which CTI uses for metal to 35psi. And finally the bake out for curing CTi cures metal at 255 degrees for two hours we lower our oven temp to 165 degrees for two hours for polymer frames.  Please contact CTI for alll your custom cerakote needs, and feel sure that CTI can and will safely custom cerakote your entire pistol rather it be an all steel frame pistol or a polymer pistol.
