Hi. I am wondering what anyone would recommend as the strongest fast acting epoxy for gluing two pieces of marble back together?  I usually use the clear Bonstone, but it takes 9 hours or so to set. I usually use a strong epoxy like that to reattach pieces and then a polyester epoxy to cap it and hide the crack. But in this case the project is too far away to make two trips. 

Thanks.
