No, air-drying modeling clay is not waterproof after drying. While it may become hard and durable once it has dried, it is still porous and can absorb water. If exposed to water or moisture for an extended period of time, air-drying modeling clay can soften, break down, or even dissolve. To make it waterproof, you would need to seal it with a waterproof sealant or varnish. **

Air-dry modeling clay should be stored in an airtight container or resealable plastic bag to prevent it from drying out. Make sure to remove any excess air from the container or bag before sealing it. Store the clay in a cool, dry place away from direct sunlight and heat sources to maintain its freshness and pliability. If the clay starts to dry out, you can try adding a few drops of water and kneading it to restore its moisture. **

Remember to work slowly and carefully to avoid adding too much moisture, which can make the clay too sticky. **
