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
