Flex Seal Liquid Large 16 oz. Black

Q: Could I dip wooden chair legs in this to prevent them from scratching a wood floor?

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...

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

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?

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.
