          You can Cerakote polymer no problem. It's recommended you sand blast it at low PSI (30-40) with a 120 grit like aluminum oxide so the cerakote bonds properly. Once the paint is applied, bake it for 2 hours at 150-180 F. It works great. Any decent cerakote place can do plastics or polymer no problem.

              Surface prep is everything.

              With plastic.
              You have mold release agent on exterior.
              As stated..
              blasting will take care of that and texture it for adhesion.

                If you want it to stick you have to degrease the surface and use a low pressure blast at around 40 PSI with 100 to 120 grit Garnet or Aluminum Oxide ..... don't use other types of blasting media as they will like "profile" the surface correctly.

                Best way to degrease is Acetone but first take a rag soaked in Acetone and lightly rug a area in the is inside, if no plastic melts or rubs off then you can soak the parts for a few minutes.
