Late follow up...
Found a zinc company on the other side of town with a two day turn around, results below.
Sent to Jim and Jim sent back. Everything was quick and painless, im quite pleased with the work, again thanks
However, the cases were not prep right prior to zincing
Below, camera at that certain angle, you will notice a dent at 5:00 and scratch line from 10 to 4 on the last unit. Normally, when I get stuff chromed the chrome people will take the time to clean and buff out scratches and so forth as this is for show and their reputation. I don’t think that’s a high priority with the zinc people as they are not really in this for show but as corrosion prevention??? Regardless, they still look good, just could have been better.
