The grout throughout the rim area between the glass and the metal frame of my glass windows has deteriorated and leaks. Will it seal this?

Hello, thank you for reaching out! Many people have had success using https://www.amazon.com/dp/B00OX6OU5S to seal their grout.

I have a leak on my shower drain, would this work to seal the leak on PVC pipe?

Yes many people have had great success sealing their pipes with Flex Seal.

Will flex seal work on concrete? I have a leak in my koi pond, would flex seal hold the leak while being underwater?

Yes many people have had great success using Flex Seal on concrete. We recommend using Flex Seal Liquid on your koi pond though since it is plant and animal safe. Flex Seal in the aerosol can is not animal safe.

I have a couple of cracks in a plastic pond shell. Around 100 gallon pond. Would this seal them?

the tape might do the job--I sprayed on to a faux leather chair -- it's peeling off--I might get more tape seal..
