araldite do a product called 2015 (industrial) which is the real stuff from the family of adhesives they use to stick bits of race cars planes bikes etc together as opposed to trying to tell the public its the same glue you can stick your grannies teapot together with is used by airbus..etc etc
another popular adhesive for composites called dp420/460/490
cleaning it to get a good bond is more important otherwise your pissing in the wind whichever way you do it
