Lacquer, Varnish
A tsunami hits a tree and your hat protects you from the water, but the hat itself is now covered in lacquer. You take it off and see that it's shiny and hard and protected.
Picture your hat and all of the other things the tsunami + tree water touched. It's all been hardened with a thick coating of the lacquer.

None
You decide to scoop up the rest of the lacquer water and use it on your furniture to protect it from your shih tzu (しつ). Now it can't bite or scratch or ruin any of your things anymore!
Watch as your shih tzu tries to bite your now lacquered chair. It gets its teeth around the leg, but it's hard as a rock. The shih tzu starts sneezing and spitting, letting go. Looks like it tastes bad too. Perfect!
