tbh mate i wouldnt know, i got mine from work when i worked there.
someone used araldite once and said it was ok, me, i think its to brittle for this.
i see this on ebay and reckon it could be ok, the "sets has hard as glass" is a bit worring as it may be too hard, but it does say "UNLIKE MOST OTHER EPOXY ADHESIVES THIS ADHESIVE SETS HARD AS GLASS, YET IT IS EXTRA TOUGHENED TO PREVENT IT CRACKING ON IMPACTS OR IF BENT"
so it could well be just the job, if someone used alraldite and got away with it then this should be ok, for £4 it could be worth a chot mate
