I've seen some pretty good looking chrome paint on line, but it's pretty expensive, and I'm not sure it would work at high temperatures. Do a search for chrome paint. I can't remember the name of the stuff, but their ads look sorta infomercial-ish. Never tried any. Best bet is to use flat black high temp paint if you can live with it, or get real chrome. Not what you wanted to hear I know, but that's been my experience.
