Is there a way of telling whether the gold plating is covered with lacquer? I don't think my Casatis gold parts are lacquered, but i'd like to make sure.

There seem to exist gold platings of different quality; the plating of its toeclips is fading away, them obvioisly being of the lowest quality, while the plating of the ICS parts is very well apart from the notorious spot on the cranks. The golden parts of the frame show no sogns of wear.

If done properly and then covered with Imron clear, the finish can last. I did a frame with gold plated lugs and such in 1981 and the bike still looks like it's brand new. Yes, the bike hasn't been ridden; but that actually doesn't matter. If ridden and taken care of in the normal way, the gold would still look the same. It's that special formula of instrument lacquer that does the job.
