Product Details

KBS RustSeal is a permanent, single-component, ceramic-like coating that is applied over treated rust and forms an impenetrable barrier against salt, chemicals, acids, and other harmful materials. Rust Seal is brushed, rolled, or sprayed on after treating the area with KBS Klean and RustBlast. Rust Seal hardens with exposure to atmospheric moisture - it gets harder and more durable when exposed to the atmosphere! It's extremely durable and very resistant to chips, scratches, cracks, or peeling which helps ensure the rusted area will never be re-exposed. It's also flexible so it bends with the surface. You can install it with a brush, roller, or with a spray gun (when properly diluted) and it's self-leveling. We use it on BMW subframe repairs, reinforcements, roll cage, and other chassis work. It's often used in restoration and hot rod shops as a frame coating. It's extremely tough and durable and can be painted with any top coat. Top coating is recommended as a finish because KBS Seal will change color after prolonged UV exposure (but its protective properties will not change). This is an excellent coating to use for E36 or E46 rear subframe reinforcements, coating and sealing subframes, sheetmetal, chassis reinforcements, roll cages, and so much more.

For the best adhesion, the surface must be prepped with KBS Klean and RustBlast. These products will strip away contaminants, grease, and oils, as well as neutralize the rust and prepare the rusted areas for sealing. The KBS instructions are very clear and easy to follow. A handy 3-step sampler kit is available with enough RustSeal to cover 12sq ft (see below).

In order for the 3-step process to work correctly, you must closely follow KBS' instructions. You can view/download them here prior to receiving your order:
