Cheers everyone, I will find out and shed some light on it this week, If im at fault then i will take on the chin and learn something! Im baffled as to how this has happened, only thing i can think of that springs to mind is the adhesive was left in garrage and when i opened bag it had some lumps through it which i sived out.
Gary, yes, used high torque mixer as always.
Whitebeam, I did not have any reason to believe the matirials where out of date but good point.
Phill, Thanks for the call, much appreciated
