Bonstone Fast Set Extreme Knifegrade Exterior Fast Setting Epoxy Single Cartridge 250 ML

used this on a very large (4 ft tall by 3 ft wide) and expensive ceramic planter that i bought... and subsequently broke once i got it home :( luckily it broke into several large pieces and i was able to bond it back together and hide the barely visible cracks towards the back.... worth the money.for a little anecdotal evidence: we used to use this product back when i worked in a custom stone manufacturing facility for crack repairs. to test it we took broke and bonded test pieces back together and were never able to make them break in the same spot once repaired. they would always break in a different place... for what its worth

Followed instructions from website. Epoxy was so thick in tube it would not come out of nozzle. It got about half ways and refused to budge. Requested refund but upon printing the shipping label found that return postage not covered for this almost $50.00 tube of special epoxy. Do not feel I should have to pay to ship back a defective tube. Really disappointed in the quality for the cost.
