Though I'd start a reference thread of the new Disney+ show The Mandalorian. The helmet looks similar to Fett's but seems slightly more narrow.
maybe Alumaster/Imperiflex? they used on a lot of the marvel costumes like war machine/thors hammer etc i'm lead to believeAny of the painters on here have any idea what kind of paints you need to use to make that metallic finish!?
The armor looks like steel for crying out loud
What a paint job
