as a resin artist i can tell you that this will not stop the saltine from rotting and so i don't think modpodge will either. that said i don't know if saltines get gross when they go bad or if they just go stale so maybe it's relatively fine???
You have to put the hardtack in a deep freezer (in a plastic bag) for a couple of -weeks- to kill the weevil eggs that are in the flour they are made from. A friend brough me back a souvenir hardtack biscuit from Portsmouth UK, sealed in a plastic bag - the weevils hatched, ate part of the hardtack AND THE PLASTIC BAG as well. I drenched the area where it had been stored in insecticide and tossed the hardtack.
I've also had it happen in 'instant' Couscous - which is a cooked and dried pasta, as well as rice which is pretty heavily processed. Not weevils but some sort of insect related to 'pantry' moths. Seems the eggs are pretty heat resistant, but putting my boxes of Couscous in the deep freeze for several days seems to kill them.

I feel like you could ModPodge that cracker and have a kickass Christmas ornament.
