Troy Hurtubise's Fire Paste . . . Or Something Like It?

Troy Hurtubise is an inventor who makes things that are impossible. Like a lightweight armor that will withstand tank-killing impacts and explosions, a deadly ray gun that lets you see through walls and kill what's behind them, and (amazingly but slightly more mundane) a light suit of armor that will stand up to a bear attack. He also made up something he calls fire paste. Spray it on whatever you don't want to burn, and rinse it off with water when the danger is past.

Now there's a company selling something approaching fire paste, but apparently with more chemists involved so they know how it works, and somewhat less protection time. Still 6 to 36 hours may just be enough to keep your jumbo loan-required house in the "don't you dare clear the undergrowth" forested hillsides of California intact while the worst of the fire rages around it. They call it Barricade Fire Blocking Gel. It also sprays on and rinses off.

If you live in wildfire country, you might want to look into it.
