Has anyone ever "chrome" coated a bike using the process they use for mirrors?

I saw an episode of "West Coast Customs", a car show, wherein they "chrome plated" a car using a spray-on process. The coating is actually pure silver (not chrome) and there is a clear overcoat so it does not corrode. It is a commercial process but does not rely on plating chromium. IIRC, it was a conversion coating - they spray on a silver compound and immediately convert it to pure silver using a second compound coming from a second spray head. I know, it sounds crazy but it worked, is commercialized (so it is credible).

Any ever heard of this or used it?
