In my experience deyellowing is only temporary

It does make the cases look good for a while though. (:
I can believe that the effect is only temporary--the action simply
cannot go any deeper than a few microns. All of which goes to show that
if you want a more permanent color, there's always paint. I have
equipment that's made from high-density polyurethane foam (no special
dies or forms needed for injection molding) finished with a coat of
paint that's more than 30 years old. It looks as good as the day it was
delivered.
