Instrumentation is perhaps one of the trickiest elements to refurbish; U.V and physical damage can often leave it functional but aesthetically unacceptable to the enthusiast.
The easiest way to refurbish instruments assemblies is to renew the damaged components - in fact if you are seeking perfection, as most owners of Japanese classic motorcycle tend to do, this is the only realistic recourse unless you have specialist knowledge and tools - professional instrument restorers can be likened to watchmakers!
