I usually use West System epoxy for everything. What if one was to seal off the compartment first, as RG did with his balsa core deck in his NS Dinky album, and then use this thinned epoxy to bed the lead. That being said, I've never done anything with epoxy... so, all of effort may not be justified, Bill From Randys Album: "To protect the top sides, all holes were epoxied. To do this I taped the underside of all the holes and filled each hole with penetrating epoxy. Some of the holes received 3 to 4 applications as it would soak in and disappear over time. Penetrating epoxy is amazing stuff! It takes 24 hours to cure and is light enough it will find its way into any void, nook or cranny. It took more than I anticipated, roughly 1 quart, but the protection is permanent."
