Re: fixing canvas snap
I use the regular jb, have used the quick set but don't think it is as good.
JB doesn't have any strength when wet so if you put the screw in with the jb you would have to hold it for 2-3 hours till it set up so I would fill and drill.
The secret to using that is to let it set up for 24 hours, if you mess with it it isn't nearly as strong.
