fill a large 1-2" crack in a driveway?

Yes many people have had great success using Flex Seal Liquid to fill cracks in their driveway.

Is it heat proof? I'm trying to seal some wood that will be subjected to very high temperatures.

Flex Seal Liquid withstands normal environmental temperatures. It is not meant for extreme high temperatures.

Can you apply it to a back deck or patio that gets lots of use? And will it hold when patio furniture will be scraping the deck constantly?

Yes Flex Seal Liquid works great on patios and decks. It will waterproof nicely, and also adds a little bit of a grip to the ground. Just make sure to let it dry 24-48 hours before putting the furniture back on it.
