Instructions for boats under 12 feet: 1. Deflate the boat. 2. Inject 1 quart (32oz) Interior Sealer equally into all the air chambers. 3. Inflate the boat. 4. Shift the boat side to side and bow to stern at a 45 degree angle until the sealer has circulated and coated all inner surfaces of the boat. Sealer has the consistency of water so it is easy to apply. 5. Let dry for three hours. Boat is sealed! ToobSeal has an indefinite shelf life and can be stored anywhere.
