    • Product works great, container broke

The seal on the backend broke causing glue to shoot out the wrong end. Used as much as I could on a few different things. The glue itself works amazingly well. Just bought another 2 tubes.

    • Works as it should

Used this to fill in holes on my homemade solar charged 12v battery pack. Squeezes out of the tube easily and seals very well but is nice and thick. Color is clear and clean. There's not an extremely overpowering scent. Seems like it will work well and last a long time.

    • The good, the bad, and the sticky.
Color: Clear Size: 3 Ounce
Overall, this product works well and is safe for aquarium use, which is great peace of mind for fishkeepers. The Pros: It's definitely aquarium-safe, and the set time is accurate as advertised. The Cons: Be aware—it has a strong chemical smell. While it's expected for silicone, it's quite intense. The Caution: The silicone is sticky, which is normal, but the real issue is the packaging. The tube is made of metal, and if you squeeze or roll it a bit too hard, it can split open, leading to silicone spilling onto your hands. I’d recommend wearing gloves to avoid a mess. In terms of functionality, I would recommend this product for aquarium applications. However, the packaging could be improved, as I ended up losing a fair amount of silicone due to leakage. ... show more

Color: Clear Size: 3 Ounce
I needed some silicone to cover some cable holes and it worked great. Easy to squeeze out and get into tight places with the cone tip. No mess at all and stored away for the next use.
