Good day to all!My question is:What preparation, or what type of primer do I use on zinc plated brackets? I want to finish with one-shot enamel. Thank you in advance for your advice.

When zinc coatings (galvanizing) are pickled with vineagar or muratic, some areas do not etch completely and can fail after many years or days. You can be assured of a good finish durability if you prime the CLEAN surface with acrylic primer such as Chromatic waterborne Universal Primer 1008. Other acrylics work to some degree but we reformulated this one some years ago to resist the oxidizing effect of the zinc/water entrapment.
