Digital BW, The Print

My son's classroom wants to use some photos I took and will print on 
photo rag for a "decoupage" project.  Basically, they seal the photos 
using this stuff called "Mod Podge" onto something like a serving 
tray.  Makes kind of a "laquered in" look.

Anyway, my question is whether prints made with the EZ inks on a C86 
on 108 photo rag can reasonably be expected to not smear or run 
during the application of this mod podge stuff.  I don't have my inks 
yet, so I can run any experiments, and by the time I get the inks, 
time will be short.

Are there any sprays that'll "waterproof" the print for the few 
minutes it will be exposed to really wet mod podge?

Thanks.
Matt
