im in the UK so probably not much help. im sure there are a few guys in the US who could do the switch for you would be better than sending all the way back to China as it takes a very long time to send back.
Are you still doing relume work? I have a Whoopy dial and a set of silver hands with white lume. I would like to have them relumed to match and maybe lightly aged. If you are doing this, what do you charge and what's the turn around time. If not, can you point me in the right direction?
