Do you have a reference for this?  The literature that I've seen 
pretty much faults the stabilizers and plasticizers as well as 
outgassing of same.

I'd think that if a simple lacquer coating worked, museums could save 
a lot of money by not pursuing grants and holding conferences, 
publishing papers and books and generally agonizing about the 
subject.

FWIW, I've used a product called "Midas Finish Seal Lacquer" marketed 
by Rio Grande (the jewelers' supply house).  It's primarily used to 
seal jewelry finishes for display and can be easily removed.
