Yes, gatorfoam has pH 5.5-6.5 according to the Pres-On chart (see 
below), but dibond and sintra are neutral.  Has anyone tried the "back 
mount" boards?  They mount to the face of the print with clear, acrylic 
adhesive - if it reduces bronzing, doesn't bubble, and is clear enough 
might be a one-step solution.
