A++ Buy


helped me reseal my 110 gallon tank life saver.



In ANY resealing project, prep-work is key. Get the old out "completely", clean, clean, clean, and let it fully dry. This product works like a champ and dries more clear than ANY other product I've used, EVER!!! Do yourself a favor and buy it in the "caulk tube", you'll acheive a more uniform bead than using the toothpaste tube. I've been keeping fish for over 30 years, and have resealed more than a few times.

works great, but do it right.


This stuff works like a charm. Like the other reviewer mentioned, it is going to work best if you remove all of the original silicone. New silicone will stick better to glass than to old silicone. What I would do is carefully use a razor blade and get a good angle and it should cut it right out. Then add the new silicone, nice and neat on the sides and I just slather it on thick and globby on the bottom. Once you're gravel is in, you won't see it anyway.



this stuff works great it s very strong! becareful that dry very fast very with this silicone i would buy only this one again
