This is the POR-15 Caliper Painting Kit in Red, part number 42839. It includes everything needed to **clean**, **prep**, and **paint** four standard car or truck steel or aluminum brake calipers. It comes with POR-15’s 3-Step Stop Rust System—Cleaner/Degreaser, Metal Prep, and Rust Preventive Coating—plus POR-15 Caliper Paint in red, applicators, gloves, and detailed instructions to achieve the finish properly.
The materials are high-performance coatings: the Cleaner/Degreaser removes grit, grease and oxidation; Metal Prep etches the metal leaving a zinc phosphate coating to boost adhesion; the Rust Preventive Coating provides a permanent corrosion barrier; and the Caliper Paint gives a **ceramic-like finish** that resists fading, heat, and debris. All components are engineered for durability and to work together as a system.
With the full system applied properly, the finish holds up in the extreme heat and mechanical stress of brake use. The red Caliper Paint included withstands temperatures up to **350 °F**, resists chipping, impact, and road-borne debris, delivering both protection and upgraded appearance. This kit is intended for those wanting lasting results with professional-quality performance.
