This was back in 2020 and took between 3 and 4 weeks if I recall correctly.
One thing to note about hard chroming a CZ: The frames are cast so there is a possibility of finding a few small pinholes (voids from the casting process). The factory polycoat is thick and fills everything in, while hard chrome is a very thin layer. I sent a Shadow 2 and an 85 Combat to APW for hard chrome, and the owner Bob Cogan called me to let me know the Shadow 2 frame had two or three very tiny pinholes on the right side of the frame. He informed me that they could attempt to buff them out but that can open a can of worms if the void ends up being bigger under the surface, so I told him to just let them go. They are super tiny but it's just something to be aware of. On the other hand the 85 Combat frame was perfect.
