How do I prepare parts to be anno'd?

[scottieb]

All of the parts at present are anno'd and I'd like to send them to be re-anno'd.

Q. Does the anodizer prep the parts for this?

Q. Can parts be anodized if they are already anodized?

They should do all the work that is what you are paying for
I think so but the color may not match

1) Anodizers will prep, but disassembly should be done by you.
2) Yes, the old anodizing will be removed.
