      Instructions

      How To Use: 

      1. Shake thoroughly.
      2. Remove the valve core (valve core remover included with 1 Liter size). Secure the tip over the valve and squeeze to dispense. Or you can squeeze the measured amount into the partially seated tire. Carefully rotate wheel 180 degrees, then complete seating.
      3. Inflate using a 2-stage pump. Spin the wheel at an angle to seal the tire beads.
      4. Note: Tire porosity varies significantly between tires. Both porosity and climate can affect sealant longevity. Refresh as needed.
