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.

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.

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.

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.

Best product ever for water proofing and sound dampening on car

This stuff is amazing. I actually used it on the floorboard of my vintage VW and under fender wells. Very durable product and good sound dampening, I used paint brush and paint on very thick. Worked great and basically put a solid layer of rubber on my car for good protection from elements.

Works great!

Works great. Had a leak in the roof vent that was ruining the ceiling in my laundry room. So far the leak has stopped and I’m so happy I didn’t have to call a roofer.

Great product!

I bought this to paint the bottom of my birdcage tray, and it works wonderful and takes very little for a thick coat.

Flex Seal I love you

I should be a spokesman for Flex Seal. I always have everything they make in all of the colors on stock and when running low I stock up like I just did. This stuff is amazing. I know from using at my home, our camper our sheds just how well this really works. I have told so many people about this they all stock up as well. A few years ago a tree branch came down thru my shed roof. We had to cut the branch just to get it out of our shed. Well I grabbed my ladder, Flexseal tape and spray and went to town. 2 years later it is still holding well. I can't say enough

Works ok but if you lay a thin layer it will peel and come off easily
