Here at Hewlett-Packard (Andover Division), we use EPROMs regularly to
store microprocessor code in our medical products.  We cover the quartz
windows using standard, adhesive paper labels.  As one responder noted,
commercial users like to label their EPROMs by printing on the labels with
a dot-matrix printer prior to covering the windows.  These paper-based
labels have proven completely reliable for use in medical products.  Do
note that these EPROMs are inside closed instruments, and probably never
see the light of day.  

Moral:  if your parts are lying on a bench, exposed to flourescent lights,
  etc, just let your random papers, databooks, schematics, manuals and
  sandwich wrappers cover them up.  That works pretty well, too.
