From what I've read, Dupli-color Cast Coat seems the way to go.

Seems like all the other brands don't look like natural cast alloy.

Easiest solution is probably just high temp silver paint

Cast aluminium tarnishing (IMR22C)

G'day all,

While I'm in the process of putting my engine back together, I want to sandblast all the cast alloy bits in the engine bay.

Does anyone know what I should use to stop them from tarnishing again?
I was thinking clear powdercoat but I've heard it can go yellowish.

Thanks.
