Bob;
If that blooming effect is what I think it is I too have noticed it in plastic cabinets, particularly those of a dark colour I think it's the dyes they used to colour the plastic, whilst they were blended relatively consistently when the cabinet was made I think maybe age, and U.V has caused some sort of shift. In some cabinets it looks almost like a grain, which is much more noticeable in something like Catalin, but polystyrene seems to have one too, likely from being injection molded. I've also see light spots where the plastic was exposed to battery acid, or some sort of solvent, and they ended up bleaching out somewhat.
Regards
Arran
