on a serious note though, i actually never use araldite. have always used the liquid two part epoxy’s that the aircraft lads use in bottles…and have never had any problems with deterioration or degredation.
however i DO use the better quality types such as DEVCON or ZAP.
i do find though that even with these they do have a shelf life, and towards the end of it, they don’t set and cure as hard as when the bottles are new.
not like me to be serious especially when i’ve just come back off me ‘olls.
