AMAZING! Used this stuff on a 100 gallon CountyLine Oval Galvanized Stock Tank. I use this tank for my 4 turtles and turned it into an awesome display of amazing turtle habitat. One of the little buggers that's too smart for his own good likes to bite on things, and I'm thinking he created a hole (I don't know for sure, Lol), so there was a never ending leak. The hole was on the welding seam and was maybe a quarter of an inch long. I did have to drain the tank and dry the area in order for this to work. Its toxic until it is dried. After checking to make sure there were no other holes, I filled up the tank and Voila! NO MORE LEAK! I would definitely recommend this.

This epoxy product worked like a charm. I have a large concrete birdbath that was leaking. We let it dry out before repair even though it's marine grade, but then my sis-in-law helpfully refilled it the morning we were going to do the repair. So we bailed it out and let it dry a while but it was definitely damp for the repair, but this stuff adhered like nobody's business! Easy to apply if you've ever iced a cake, lol. Was in full sun during drying time and there was no blistering at all. So far so good, water tight for over a month now.

I like having this larger quantity!Given that some of my projects are not so petty. I first tried it out in a smaller packaging. I'm actually using 3 different products. My old FAV is no longer available--EverCoat TenSet. What I like about this is: the consistency is easy to mix and apply; the workable time is extended, gving me time to smooth and shape. What I didn't like was the very rough finish I was getting. Then I later saw that I could wet my finger and smooth it a bit. In photo, the piggie suffered from out door winter weather, and I have repainted him twice before. But this last years winter, "washed" his tail OFF, lost half of one ear, and a hole through the other. Also lost his eyes and brow. So, I'm experimenting with product and rebuilding. That's why you may notice 3 product colors. Also widened base of the frog to not tip over. That's how he lost the crown tips. Rebuilt with JB SteelStik.

there are some pro's and con's to this product.

Pro - hard as a rock once it dries
Pro - easy to use and resealable syringe
Pro - i was able to drill and screw into it after it hardened

Con - its not white as advertised, more of a faint blue grey so it shows on my white boat - this is why its 4 stars but the problem is i can not return it as its used and attached.
Con - its not gel coat friendly
Con - a realistic cure time is a min of 48 hours
Con - doesn't lay smooth sanding is required.

I purchased this to repair ceramics and it has worked perfectly. I love that I can mix just as much as I need to use immediately, though I do not feel rushed as it stays workable for a while. I had used some type of crazy glue for these repairs in the past, but I have found that using this is more effective and provides as strong a bond. I have used rice in a bowl to help me stabilize the ceramic at time of gluing. Great product.
