I have been working closely with a local plater for about 25 years and I always have him chemically strip my parts. It removes the old plating down to the copper and then I can hand finish from there to get the pits cleaned out.

Blasting can cause small bits of media to get embedded in the surface and screw up the plating.

I make a lot of new parts from ZA alloys never blast them before plating...
Have any of you ever tried soda blasting it is definitely not as abrasive as sand beads or glass
and is a process I have been using for about 10 years I have found that it will pretty much remove any thing and leaves an almost flawless surface
