Sounds like duracoat? which does suck.My first Cerakote was a revolver. Coating was so thick the revolver wouldnt revolve. Took being left for a few months before the problem was resolved.
Second was an old Sig P6. Inside the slide was so thick that the barrel dropped early and would not assemble. Required a Sig Smith to resolve the problem.
I know a lot of guns are factory coated and Ive seen the coating chip relatively easy. When compared to other treatments, Cerakote seems pretty $#!htty.
Perhaps it was just the coater or maybe its the product. Either way I have lost all faith in Cerakote for anything I plan to do in the future.
Im sure there are great experiences but, Id like to hear any issues you may have had.
