## Questions & Answers

**Q: Could I dip wooden chair legs in this to prevent them from scratching a wood floor?**
A: Yes, you can dip wooden chair legs but as you use the chairs the bottom will wear off. If they were my chairs I would use felt pads that you can find in any hardware store.

**Q: Would a metal surface become insulated electrically after this was applied? Thinking of a tight car battery compartment...**
A: Not enough to protect the battery from eventually shorting out. I would recommend securing a thick piece of rubber between the battery terminal and the metal close to it.

**Q: How long dose this take to dry**
A: It takes at least 24-48 hours for Flex Seal Liquid to dry based on the thickness of your application.

**Q: My child has a basketball post with a plastic base that holds water.  The base has a leak. Is this product suggested? If so, any prep suggested?**
A: Anything works better with a little prep., sandpaper and clean.  It should do well.  Also as a add the new tape would probably work better.
