JD, The pics that I have seen of your parkerized work looks much smoother than the parkerized finish on my factory 870Ps. So I ask, taking into account that parkerized finishes don't photograph well, is it the media that you use to prep your guns less course than the media they use at the factory or has your guns been soaked in oil and the park has just soaked up that oil to the point of looking more smooth? Or is there something else I'm missing? (time in the parkerizing solution, type of solution, etc.) Thanks for your response!
