Will yhis work on the bottom of a black water tank?

We used it to repair a separated seam on the drinking water tank for our camper. I don’t see why it wouldn’t work for your application. It’s held for a solid year, with several uses.

My coolant tank isn't cracked but has that white spiderweb look on the top near the cap, would this cover that section, to prevent it from cracking?

I think so. My tank had a small hole and it was very brittle in the area with cracks and it has done just fine for several months now. Much cheaper than paying $100 bucks for OEM tank.

Will this work on rubber?

Does it say it works on rubber? If it does then yes otherwise buyer beware. Please read shut the product uses and descriptions before asking this type of question.

Which is the best sealent for stopping leakage in sintex water tank

I ended up using gorilla glue, it was easy to apply and leaves a clear watertight seal. Remove the tank, drain it, wash it well with soap and water, dry it well, apply gorilla glue to the cracks and let dry, then water test before you reinstall the tank. Easy, clean and works great, has lasted over two years since I repaired.
