I just got my CZ 82 back from refinishing. I had purchased it from Classic Arms and the finish on it was flaking off. So I sent it to Ahlmans to get their re-blue matt finish put on the CZ82. I sent "as is" not dis-assembled.
Ahlmans did a fantastic job! They completely dis-assembled the CZ82 and re finished all of the parts (slide hammer, frame, etc.). The matt re-blue gives the CZ82 a classy look. If your interested in refinishing your CZ82 consider Ahlmans.
