Castle® Meta-Seal™ Brake Squeal Eliminator is a spray-on metalizing treatment designed to prevent brake noise at the source. Micro-fine aluminum particles form a molecular bond with rotor/drum friction surfaces to end annoying vibrations and brake squealing. Effective on all brake systems, Meta-Seal™ extends the life of the brake components. Benefits last for up to one year or 10,000 miles of average driving.
