Rinse & Seal is a perfect way to add protection to your vehicle's paintwork quickly and easily and giving you up to 3 months protection. You can apply it in 2 easy methods, once the car has been washed and rinsed and when still wet add 100ml into a 1ltr foam bottle, top up with water and use as if it was Snowfoam. Spray over the car and allow to dwell for a minute and rinse thoroughly with a pressure washer. You will see the water just sheet off. Alternatively put 50ml into a 500ml spray bottle and spray onto wet panels.
