Unfortunately, you can't lacquer polished metal mate. The surface needs to have either primer or base colour on it for thelacquer to adhear to. One way may be to get it anodized? Not sure if they do a clear anodize though. Best bet is to get the metal polishing kit for your electric drill or grinder mate. It's still a lot of work, although easier. And the finish you get is highly polished, and lasts a lot longer. I did ruby's with the metal polishing kit on my drill, and it's not been touched since I done it. Still looks the same as far as I'm aware. Or.................you can have it chrome plated (costly) or if I ever get my business up and running, you can have it chrome painted. Still costly, though not as dear as the plating. Looks amazing, and you can lay on high temp primer as far as I know, so shouldnt get any issues with heat.
