A tip for the Apache cases. After plucking out the cubes to form the compartments, use spray can Plasti-dip to seal and lock all of the foam cubes together.
This will seal out moisture, add strength/rigidity to the foam, and keep gun gun chemicals from degrading the foam.
It usually takes 3-4 coats. 1st coat is a light "wetting" coat, then apply subsequent coats until it's to your liking.
