Piper - 5 min epoxy is good for the spa ... if its a small plane!!! Heck it can be used to join wings for smaller planes. I would lo to see someone use 5 min epoxy on a 60/90 sized plane ... hehehe ...

I never use a heavy blob of epoxy ... I use 90 mins epoxy (personal preferrence only) and its a thin layer, usually not much will ooze out. Built 25 planes last year and none had their wings failing on me even when I fly like a mad man. Heck ... they do not even come apart much when I bring them to meet Mother Earth!

I am totally sceptical about CA as CA is only really strong when the surfaces mate very well (no funny comments ok!). CA is a liability if there are gaps and somehow I am not sold on the idea of medium CA (sorry).
