Gorilla Epoxy Ultimate

This stuff is crazy good. Very effective. Easy to use. Once it does on, you will never get it off. It dries in 5 minutes. After you mix it, you only have 5 minutes to apply it or it will get hard and gum up. Once on, it seals well. I had to fix the cracks in my dashboard. I applied it and it sealed it. It filled in the cracks and now looks like one complete unit. I do not see anymore cracked lines. The black is a perfect match. This stuff is super strong. It definitely smells very bad but after 12 hours the smell is gone. I highly recommend this. It works. I always buy gorilla glue for everything.

The epoxy works wonders. It's black in color so it didn't look great on the clear acrylic that it was used on but it has held in cold temperatures and under pressure. It dried in minutes and cures over night. Kind of tricky getting it out of the tube but you can use the package as a tray to mix it. Very convenient.

Used Gorilla Epoxy Ultimate to install new grilles on my truck and this stuff did not disappoint. The bond is insanely strong—dried rock solid and bonded the metal to the plastic perfectly. Once it set, there was zero movement and it feels like it’s part of the truck now. Super easy to work with, sets up quick, and gives you confidence it’s going to hold long term. If you need something heavy-duty that actually delivers, this is it. Highly recommend.

Works great, hardens quickly, holds tight.

Good stuff, quite durable and strong. My only gripe is that it turns into something like a rubber texture instead of hardening. I've made sure ratios are right and all that, but still seems a touch soft. My guess would be that helps make it more flexible, but that's not necessarily what I was going for. As a word of warning, this stuff is quite toxic. Make sure you have plenty of fresh air.. and I do mean fresh moving air in good quantities. Outside if you can.

I used this for installing a black granite counter (the seams between pieces). It worked beautifully. It was the only black epoxy I could find and the final results are fantastic. The bond is rock hard and strong. It sets quickly - you really only have 10 minutes max before it's not workable. It goes on non-flowing so it would work well on vertical surfaces. Extremely easy to apply - just break the tab, squirt onto scrap material and mix with included applicator stick. The only thing I needed that wasn't in the package was a standard razor blade to press it in the seams and shave it off (which you should do before it completely sets). You would think it would be a nightmare to clear up but it cleans up amazingly well and quickly with acetone. Rubbing alcohol works too. Just apply it with a paper towel and it instantly starts to dissolve (turns bluish!) . I did this after about 10 min. I think it will be much harder or impossible to clean up like this if you wait much longer than 10 min. Because it's a two-part epoxy it stores well for continued application at a later time (no drying the tip shut like regular glue). As far as quantity, I needed about 2.5X as much as I originally thought, but that might just be my inexperience. I was not able to return the one leftover tube because it was "unreturnable". But since it stores well I now have a tube of great black epoxy if I need it!

Worked as says on package. 100% waterproof. Like welding things together with epoxy basically.

I used this to build a set of artificial nails (more like claws) - of all the materials I've tried for this project, this turned out to be the most durable so far. It's also quite easy to work with and cures quickly.

Husband loves this stuff.
