You can do it - but it would be with paint.
Check out some car enthusiast forums - they are smoking and blacking chrome all the time. They use something called Dupi-Color most of the time.
I would look into the "Alsa Killer Chrome" (it is ground metallic pigment and can do some pretty cool stuff) http://www.alsacorp.com/products/kil...llerchrome.htm
Once you treat it, I'm not sure about the durability - but it must be pretty good if these guys are using it on car rims, etc...
Show some photos if you do it!
