Is it possible to refinish cast aluminum letters?

[ChaseO]

I have been asked for a quote to make some existing cast, brushed aluminum letters match some new anodized gold, cast aluminum letters. I will likely quote new as well, but since these are 15" characters and a bunch of them, I was curious if anyone had ever sent old letters back to Gemini or someone similar to have them anodized. I figured I would call Gemini tomorrow, but first thought I'd see if anyone on here had ever done such a thing.

Thanks,
Chase

Exactly that, holler at gemini, they'll likely receive and re-anodize for the right price, though they'd probably try to steer you towards replacement letters and all... I mean, they have a lifetime warranty, they might just send a new one for free if it was indeed their product.
If they are just ancient cast letters, they could be from ARK Ramos. Not sure of many other older foundries.
