Adhesive and sealer compatibilities

If anyone knows,

What primer/sealer will stick to Titebond 3 / silicone bronze / Joubert 4mm Okoume? Urethane? (I know it's an epoxy centered universe, but I am allergic....)

( for a wee sailing canoe, who will be playing in the water, but sleeping in a heated garage.)

And as long as I'm on a roll, will the following stick?

Urethane on dried Liquid Nails?

Liquid nails on dried urethane?

Will the fumes from dried urethane melt extruded polystyrene?

ask these guys http://www.glueguru.co.nz/

 

Liquid Nails has absolutely no business on a boat, it's just not formulated to handle the environment or stresses. It is good for dry, static loads, but that's about it.

 

plus when it dries completely its hard and has no flex !!

 

LN holds extruded polystyrene together like nothing else I've tried. I'm looking for 2" longitudinal xps panels in light compression to keep flat vertical bow plywood skins from flexing in, not structural support. (take a look at Phil Stevo's IC blog to get the idea.) Do you think that longitudinal wood strips supported by wooden lateral triangulated cross bracing (like a Warren Truss) glued and screwed or nailed would be more effective than xps (as far as weight goes)given a non epoxy environment?

Thanks.
