The KBS Ultimate Quart Size 3-Step System kit includes enough products to Clean, Blast and Seal a full-size car or truck frame, or any 50 sq. ft. area with 2 coats of paint coverage AND Cavity Coater and Wand to seal up the inside of the frame. KBS Coatings' 3-STEP SYSTEM of Rust Seal (a rust preventive coatings), KBS Clean (an industrial strength water-based cleaner / degreaser) and KBS Rust Blast (a powerful rust remover / metal etch) is the most effective rust and corrosion prevention system available today. Rust Seal chemically bonds to bare metal to form a permanent, moisture resistant finish that is flexible yet won't crack, chip, or peel. Because Rust Seal is moisture-cured, this superior coating is made even stronger by continued exposure to moisture. Rust Seal is also highly resistant to some of the most aggressive chemicals such as acids, alkalis, salts, abrasive materials, fertilizers, coal dusts, solvents, oils, and other refined petroleum products. Cavity Coater with a KBS Cavity Wand gives long lasting protection for those hard to reach enclosed cavities such as rocker panels, boxed frames, inside doors and fenders, deck lids, tailgates...and more.
