CERAMIC. FOAM. RINSE. We are changing the industry with this! Your lids are about to be blown!! This product can be used monthly after washing your vehicle to coat your vehicle. First clean your vehicle thoroughly. Second put 2-3 oz. in a Foam Cannon/Garden Hose Foam Cannon (sold separately) and fill the rest of the foam cannon with water. The bottle is 16 ounces, so it will last a long time! Apply in a thick lather foam and rinse immediately. Do not apply in direct sunlight. Do not allow to dry on the surface you are washing. Can be sprayed over soap to help rinse but works best if you rinse between soaping and the use of this.
