Powder Coating Pot Metal

2001

Hi everyone,

I am restoring a 1955 Seeburg JL jukebox. The machine has lots of chrome plated zinc castings which are heavily pitted. I will not be re-plating the chrome due to the expense. Re-plating a 50's vintage juke often cost more than the machine! A friend has a small powder coating rig and has offered to powder coat my castings. He has had great success powder coating parts for his dragster. What sort of prep work is required of a pot metal casting before powder coating? Should I sand away all the chrome? Must I buff out the pits or will the coating "float" them full? I am pretty much limited to "hardware store" type supplies. I am lost when it comes to the chemical washes...

Thanks in advance for any help!
