The Best Premium Wax! It Cleans, Shines, Seals and Blocks Rust. Just spray it on and towel off. No other wax provides protection along with such a long-lasting shine. Just wash or rinse vehicle to remove surface dirt. Apply Bull Frog Fast Wax with Rust Blocker, making sure you spray hinges and door frames. Then towel dry with a soft, clean, dry cloth. After waxing, Bull Frog VpCIs go to work, sealing and protecting metals with a self-repairing ‘Molecular Umbrella’ that seals out the air and moisture that cause rust and corrosion even through paint and other coatings. Should the Bull Frog ‘Molecular Umbrella’ ever be scratched away, VpCls in the adjacent wax migrate through the air to form a new one.
