Jay Leno's Garage features both traditional methods of restoring our beloved vehicles as well as cutting-edge technology to assist when the going gets especially tough of costly, in fact it was on Jay's internet show for Big Dog Garage that I first found out about 3D printing new car parts a few years ago. Jay recently featured an innovative German who came up with a novel method to realistically coat metal parts to make them appear like chrome. No, this isn't the rattle can junk we always believe we can "will it" to look like chrome tho it never does, but rather the system borrows from mirror resurfacing technology to apply a thin coat of true metal material onto the surface in a process that looks almost magical to observe.
You will see in the above video that there is no need to worry about runs or drips, the stuff essentially lays itself on in the right way, dummy-proof. You do need to apply a clear coat to protect the finish, it would then be cared for just like any other painted surface would be making it less ideal for contact parts like bumpers, but for trim and interior bits it really looks to be an innovation on the rise.
