Just be careful if blasting parts/hardware that you don't add texture to the surface as that will show through in the final product considering the thin plating coating that will be but on.
Think we're all choosing to "better" the finish of the bright zinc finishes we get today to something slightly duller to reproduce the original look. I've been using the fairly short vinegar rinse lately in addition to using it to remove the dicrhomate if I do just a single batch of everything
Often try to get access to an additional parts car when doing plating that way I hopefully have two of everything, at least that is the plan. So I can choose the best for the car and have backups or inventory for other projects or needs.
Sure miss the old days where instead of cleaning bolts and nuts dad would just load up coffee cans full of them and take them to the platter. A couple of days they would return all the same finish, clean (no old paint or oily) and ready to use on what ever we were working on. And for $5-$10 for everything
