Used this sealant to fix a crack in my tank’s glass. It applied smoothly and stayed put even on vertical surfaces. After a few weeks, the fish showed no signs of distress. It’s durable and doesn’t sag or crack over time.

Great product for aquarium repairs. No primer needed and it cured well without any leaks. My saltwater tank has been stable since I used it.
Vanessa Gray –
Works well for sealing joints. Took a bit longer to cure than expected, but once fully set, it’s strong and doesn’t move. Fish are fine after a few weeks.
