Anyone zinc plate steel?

Does anyone have experience / the setup for zinc plating steel fasteners and small parts? I’d love to chat about it and maybe collab on plating a bag of fasteners and small parts from my resto car.

Or, if anyone knows a spot I can send the fasteners away to, I’d be interested in that too. None of the plating shops (that I’ve found) in Austin, San Antonio, or Dallas do small batch / barrel plating.

CMT in Round Rock will probably do It.
I am in the initial stages of getting an electroless nickel setup but it’s a way out.

They were the first ones I called — unfortunately they don’t do barrel plating, only plating by the part. For nuts and bolts that would be prohibitively expensive.
