and I will add... the Retrobrite... we are not sure what the long term effect is.... It would be a real bummer if 50 years from now the object decomposes.... OH NOOOO!!!!

That is what the Air and Space Museum has done for a while - a very thin wax coat covers the original, untouched finish, and a new paint job is applied onto the wax. Apparently it is easy to strip off, thus a reversible portion of a restoration, but I think the paint is not durable at all (which is why you should not touch things in museums unless given permission). I am not a fan of the Retrobrite process, although I have never tried it out. In my mind it just seems wrong. -- Will
