The powder coat finish on my 1996 so-called Military Model CZ-75B has held up very well.
Q: "What is the finish called "Black polycoat?"
A: Black polycoat is an electrostaticly-applied powder coating
that is then oven cured to a hard shell. The coating is applied over a Parkerized or Phosphate finish which is very corrosion resistant in itself, the parts are then racked, given a negative charge and sprayed. This charged attraction literally draws the coating to the parts, giving the parts a uniform finish and reducing overspray. The parts are cured in an oven, producing a tough finish that meets Mil. Spec.
