I've seen that chrome paint mentioned. It is very expensve, especially if a large part is done (by "large" I meant anything Harley gas tank size or larger). It does look like chrome if done right, it basically works like a mirror. First part is a high gloss balck base, which requires the item being painted to be absolutly perfect, as imperfections will show. The next step involves a special topcoat that has metallic particles suspended in it. Not silver paint, more of a clear with silver paowder in it. The base actually provided the shine, the silver gives the reflectiveness.
There is a similar product in the model car/plane hobby that works the same way, it's rather pricey, too. Pricey enough that you wouldn't want to do anything bigger than maybe a small side badge or dash emblem.
Alclad chrome laquer. I have personally used this product, it does make for convincing chrome.
