Review on Clear Gorilla 2 Part Epoxy Syringe, 5 Minute Set, .85 Ounce (Pack Of 6) by James Arellano

In the bathroom, we have cultured marble countertops and a matching (vertical) surround on the jacuzzi-style tub. While removing the tub surround to do some plumbing repairs, a hairline crack formed on one end of a 6ft panel, reaching roughly 2 ft in length. Rather than replace the panel, I decided to epoxy a 3/8" plywood splint to the back of the panel, to maintain alignment of the two sides and hopefully prevent the crack from propagating further. I've used Gorilla adhesives before for woodworking projects, so I chose this epoxy product for the job.My plan was to spread a thin layer of mixed epoxy on the back surface of the panel and then lay the plywood directly on it to form the splint.So - My product-use experience:The Gorilla Epoxy package instructions call for first inverting the syringe and bleeding air out of both sides, to assure smooth flow of the two components. Makes sense. These materials are very viscous however and one side cleared faster than the other, suddenly shooting a blob of liquid out the end - It was startling and was met with a few choice words as I scrambled to clean up the tile floor.The tiny plastic mixing stick (found between the two plungers and essentially a fat toothpick) is nearly useless when you have a large area to cover and need to rapidly blend a lot of epoxy - remember that this stuff has a 5-minute set time. I smeared it around rapidly with the stick, but I doubt the result was homogeneous. When I set the plywood on top, I immediately moved it around clockwise, then counter-clockwise to better-smear/blend the two components.I then set full 1-gal paint cans on top of the plywood, as there is no easy way to clamp this together, and I gave it 24 hours to cure. The next day, there was some clear, mildly sticky bleed-out along the edges of the plywood. It looked sloppy, but that side isn't visible once the panel is installed so.Fortunately, the epoxy seems to have fused the plywood to the stone panel fairly well. I doubt that I achieved the intended 3300psi bond strength, but this panel serves a largely a cosmetic service so there's not really much load on it.I wouldn't call the process "easy-to-use", but the plywood splint looks like it's doing its job and the panel is now reinstalled. The hairline crack is barely visible, so as long as the panel doesn't move any more, we should be good. Close-enough I guess.Rating:They lose stars for the difficulty of following their instructions, butThey get more stars for making a product that sticks well even when the directions aren't followed
