Want to try POR-15 and to see if you like it? Now you can with the Super Starter Kit. Enough product to clean, etch and paint about 6 square feet, with 2 coats. POR-15® is a high-tech, high performance rust-preventive coating designed for application directly on rusted or seasoned metal surfaces. It dries to an incredible rock-hard, non-porous finish that won't chip, crack, or peel, and it prevents rust from recurring by protecting metal from further exposure to moisture. Use it to coat rusty frames, floor pans, farm equipment, marine equipment, or even a heavily corroded battery tray.
