A ZAMAC car is basically an unpainted car and/or base. Aluminum doesn't rust in a structurally-bad way, but it does oxidize, so you get smudgy-looking fingerprints. From experience, flash rust appears on the surface in less than 12 hours. Water-displacing oils, water-soluble oils, waxes, lacquers, and temporary rust inhibitors can enhance the quality of a metal finish or protect bare steel parts. It acidifies any moisture Chemical specifications for zinc alloys are given in ASTM B86 for No2, No3, No5, and No7 alloys, and ASTM B791 Cast iron is difficult, but not impossible, to weld.
