The problem with vac-metalizing is you can't do it on that type of plastic... That's not bad though. But I prefer vac-metal on 3PO is all, since he was. It's like R2's dome in reverse... It was polished aluminum and I prefer it to look that way than the old vac-metal domes. Unfortunately it only sticks to ABS and doesn't to PVC, and BAD protocol molds are made for PVC.
I'd like to see what they could do though, if they could acheive something fairly close with a highly metallic flaked paint/plastic additive.
And I agree on HK47 too... Was just thinking of possible ideas. I'd not mind it, but at the same time I'd be ok seeing him return in a multi-pack of KOTOR figures that maybe had a couple new ones, Bastilla Revan and Malak, and HK47. A nice set to flesh things out for KOTOR a bit.
