I am starting my first jon boat build-up. I have a 1436. Just wondering what kind of epoxy would be best to use to attach things. I work in aviation,so we have all the wierd,funky stuff. We can only use it for 6 months before we have to scrap it. I save it for some reason. It doesn't go bad,just FAA regulations. ANyways,we have one specifically for aluminum and magnesium. It's called Armstrong A706. It is used in the fan case,and air ducts. It is tough enough to withstand wind at over 500mph. As well as birds,water,and whatever else there is at 35,000 ft. Would this work or is there some specific type needed for use in water? Only drawback is it needs to be heat cured @ 350 degrees for 2 hours. But,it's hard as a rock.
