Can it be used to fix a slit on a hot tub cover?

Thank you for reaching out! Many people have had success in situations such as this. To ensure you apply Flex Seal Spray correctly follow the steps below: Many people have had success in situations such as this. 1. Make sure the surface is clean and dry. 2. Shake well and spray using even, sweeping motion. 3. Spray a larger area than area where the leak is and feather the edges. 4. Let it dry completely (may take up to 24-48 hrs to cure). 5. Apply several, even coats until all the cracks and holes have been filled. If you have any other questions, please feel free to reach out to us again.

Can you paint over it?

No, paint wouldn't adhere well as it creates a slick surface

Can it be used inside a pond that is leaking? Will it do OK under water all the time?

I used it in a birdbath to try and keep the water from evaporating so fast but it eventually breaks down from the Sun and water. I wouldn't recommend it.

Would this work for a leaky gutter?

Many people have had great success using Flex Seal on gutters.
