Chaps, I’m looking to paint some alloy components in satin black. I want a thin but tough coat and was hoping to use a ‘one coat’ type paint that requires no primer or undercoat. It’s not engine cases, so no need to be heat proof. Also not really practical to heat the parts to cure the paint either. So, any personal recommendations for an air drying, tough, one coat, satin black, rattle can paint, that will adhere well to aluminium?
