Rtic metallic tumbler

Has anyone engraved one of the metallic tumblers from Rtic? I have someone who wants one done, but I can’t find anyone who has ever done it. Just want to make sure it’s possible, I assume it’s some type of powder coat but I am not sure.1162645994

I’m fairly certain I’ve seen these done. Though, not that same color scheme.

I was just using that as an example.
