I'm probably a step too late. I saw an add of Hysol in Dreamworks (FL) ad carrying the type you were looking for. Hysol is a brand of Henkel (Germany). Used quite a bit of Epoxy at work over a decade ago. Henkel had a few different codes, including rubberized type & also many different CyA (Superglues). Aeropoxy buys ads prominently in RC & EAA magazines. I don't have any direct experience with it, but am not aware of any squaks. Let us know how it work out.

Cheers,

Phil
