Thank you for a very important post that is worth repeating in its
entirety.  It explains discrepancies in fading reports.  Unprotected
Epson prints in kitchens seem to be especially vulnerable.  It also
explains why coatings would have little effect in laboratory tests that
are checking for light fading only.  In addition to fumes, humidity also
seems to contribute to fading.
