Default wing saddle potting

Anyone have a good method for potting in Q40 wings with a 'somewhat flexible' material like silicone or urethane or.... Im familair with the usual 'hard' technique using epoxy based splooge. But I would prefer just like a bit of 'give' & vibration dampening. Its not a big gap, its pretty close, so the potting thickness would be quite thin in areas. Ive heard there are brands of caulking that work like outdoor paintable sealant, but I must be buying the wrong stuff. I cant get it to release clean using my usual technique of shiny packaging tape on the wing + mold release wax. I have some kickbutt mold release but silicone doesnt seem to like to cure on it.

Do you have a brand name for that glue? Im assuming is still viscous like caulking/spooge? You mean you use wax paper as the barrier layer on the wing & it releases properly from the glue?
