How about the LPI type covercoats like Coates ASI Aquamer or the
        new Dupont product? Aren't they hard/scratch resistant?

In the past we have used a Teflon coversheet with 
acrylic adhesive made by DuPont.  I'm not sure if 
they make the coversheet with a flame retardant 
acrylic.  The coversheet has been available in 
the past with .002" Teflon and .001" acrylic. 
DuPont part number is LT-0210.  Let me know if 
you need a contact at DuPont.
