RE: Materials:
EA934NA is fairly dense and brittle.
following options are avaialble...
low-density polysulfide sealant.
my favorite...
EA956, filled with glass or phenolic microspheres. Add/mix microspheres into the E956 resin until the mixture attains a semi-stiff/sticky nature. Clean area to be filled with solvent and allow to dry under 120F--140F heat-lamp. Remove heat-lamp and immediately brush ["paint"] raw EA956 resin onto the exposed core and interior surfaces of the facings. Press the potting mixture smoothly into the core [minimize voids] and over-flow the edges. Squeegee-away the excess and allow to cure. Brush-coat exposed potting-mixture with (2) coats of primer to seal surfaces and edges.
There are other commercial potting compounds available... and other "home-brewed mixtures available... look in SRMs and other honeycomb repair manuals [IE: MIL-HDBK-337].
