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.
