I'm going to disagree with that statement, I have used many quick drying epoxies for some heavy duty applications, and never have I seen the difference between that and longer drying epoxies. I will agree that if you add more of the hardener it weakens the epoxy, but as long as you follow the directions quick drying epoxies are just as strong.I think the rule of thumb is the longer it takes to set, the stronger the bond is. 24hour epoxy is stronger than 5min epoxy
yep, will do!JB Weld's my favorite too.
But with an adhesive, a good quality join depends on surface prep. Rough up the mating surfaces with sandpaper to give it something to grip.
