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.
