Oho! Great timing, DC, I've got a crystal chamber on hand that could do with some fancy finishing. I was going to go with Rub'n'Buff, but this looks like a lot more fun. Now, just as long as that conductive paint I bought the other year hasn't dried up.
It's a right shame you can't plate aluminium onto things, then you could anodise it afterwards and have a larger range of colour finishes
