We have a sample and it does look a lot like chrome, you can't tell unless you feel the weight. We are informed that the company can strip the origional chrome coating from alloy wheels and replace it with this stuff. We haven't tested it on wheels, but we have no reason to doubt their claims that it is very durable as it seems similar to the coating used on car badges which last many years. So it could be that a solution is here at last!
