I've seen these two before but they've been listed above already.
Killer Chrome and AlcladII
I think the terminatorfiles.com site had a demo of Killer chrome being used on a T-800 skull and it looked fabulous. It's a while since I've used the site so not sure where to find it. Might even been on Endobuilders.com but that site shut down. Both Killer Chrome and AlcladII look a lot better than Rustoleum (no offence xdmray). Good luck.
Apologies to Dieabolic, I never followed your link.
