It's zinc alloy. Do you have any tips for an appropriate coating. I thought an enamel paint would adhere to it?Use SolvolAutosol and a dremmel with a pad on it.
Will need to coat it as not only will it tarnish, it will end up all over your hands with black metallic deposit.
Coating may be difficult as alu alloys generally need an etch coating or it chemically reacts and blows the coating off.
