Works wonders
Found a 55 gallon tank on the side of the road that was cracked on the bottom. Used this to fix it and I still have that tank. Not a single leak.

Better than I thought
I use this to seal custom fixtures in my hamster cage because itโs nontoxic if she choose on it and it held up way better than I thought it would it also cured very quickly. I will say that it does have a very strong smell so make sure you have a good ventilation, but overall very sturdy and easy to work with.

Works great for many projects
Used it on a 20 gallon long tank that had been used for reptiles. The silicone was scratched up, shredded & missing on every side seam. I cleaned & scraped old silicone off it with a razor blade, wiped the application sites with alcohol prep pads & applied the new bead. It stuck perfectly where it needed to & bonded to the existing silicone on the bottom. It shrank down from a convex bead to a concave bead in 24 hours. I washed it out, filled it with already cycled water & had fish inside the tank within 48 hours. It didn't use much of the tube, so I also used it in an emergency to repair a drain hose to a washing machine that had holes in it. I covered the holes with the silicone & wrapped it with electrical tape. No more leaks & it dried even with an initial wet application.

Great product bad packaging tube
I love this stuff. Itโs a great waterproof sealant thatโs a little elastic but not too putty-like. It doesnโt smell much as youโre applying it, but the smell gets really strong as itโs drying. Be aware it will need somewhere to dry away from you and your pets. It takes about an hour to set to the point where nothing will fall over. It takes a really long time to dry completely to the point where it stops smelling. About a week. I used it to make a basking platform for a snake and it was super important that there was no smell before I added it to his cage. Itโs nice and strong though, and Iโm confident it will hold up to bleach when I need to sanitize clean his cage. The tube it comes in is awful. The back end of the tube always blows out no matter how careful I am. It happened to all 4 tubes I used. Quite a mess. Honestly it might just be better to cut off the bottom of the tube and use that instead of trying to get the sealant to come out the nozzle.

Great for terrariums
I use this to seal enclosures for tarantulas. The small tube is more than enough and perfect size for smaller enclosures compared to the 10oz ones that I use for reptile PVC enclosures. This is my first time using the small tube and it didnโt bust on me like others mentioned. Works great, looks good. I will continue to use in the future.

Easy to use
This sealant worked well but the bottom of the tube was already set and solid, could not squeeze sealed end of tube. Had enough to seal what I needed, but the rest was unusable.

Great Product. My main tank cracked half way down and I needed a temporary solution to keep my fish alive whilst waiting for my new tank. I applied the solution onto the crack and it was able to significantly stop the water leaking.

not useful, it is the same material used in other silicon sealants. not worth to buy. go for cheap one.

I have a butter dish with a lid that I absolutely love, however once summer came small gnats were coming through the open screen window and getting through the gaps between the lid and dish itself and into my butter. Yuck! I decided to make a gasket so the lid sinks into position and seals so nothing can get in. Worked out awesome! Super happy. Figured if its safe for fish its safe for me.
