## Questions & Answers

**Q: I have a wooden bucket ice cream maker that won't swell anymore and the water leaks out of it. Will this work with the salt brine?**
A: I am not sure if this would work. I would try gorilla glue.

**Q: Can this effectively seal a leaky window?**
A: Yes many people have had great success fixing a leaky window with Flex Seal.  You can use painters tape to section off the area you want to apply it to.  You may also want to try Flex Shot, which is a rubber caulking material, and will give you pinpoint accuracy.

**Q: Will it seal the bottom of a blow up matress**
A: Thank you for reaching out! We do not recommend Flex Seal Spray for this application, it is not meant for high pressure or temperature situations.

**Q: would this be good for a bed truck liner?**
A: Not sure, it would take an awful lot to spray a bed of a truck and we found it to be sticky when it got hot!  We used it on a gutter so it didn't matter.
