Westinghouse wc 102 md lighted sign

Has anyone out there found a square top machine with a lighted sign where the "Drink Coca Cola" on the plexiglass has turned completely white? I don't know if this is sun fading or not due to the fact that the green section at the bottom where it says "Pause   Refresh" doesn't seem to be faded at all. It almost looks like it's the result of some kind of chemical reaction or something unique to the red paint that is used on the "Coca Cola". Does anybody have any idea what I'm talking about? If so, is there any way to correct this problem? The sign came out of a basket case that I'm parting out and I just want to use this peice as a lighted sign so if it's junk, it's junk. No biggie, just wondering. Thanks for any help!
