I know that there has been a tremendous amount of talk
about removing yellowing from vintage equipment, but going forward, does anyone have any
suggestions for helping prevent yellowing of equipment on display, short of keeping them
in a dark cave? I have a couple of Apple II's that are in excellent condition with
minimal yellowing and would like to put them on display without having to worry about
damage to the plastic.

Has anyone looked into sealing the plastic items with a plastic coating?
Spray on acrylic or urethane products?
Possibly dipping in something like fiberglass resin would protect
against the atmosphere. I haven't seen signs of that polymer breaking
down - at least in equipment I have from the early 1970s.
If oxygen is the enemy then almost anything would help...
