Buying Guide

Match coating to substrate

Choose formulations labeled for metal, engine, or tire use to ensure adhesion and long-term corrosion protection

Check heat and chemical resistance

For engine bays or high-temp parts pick heat-resistant enamels or primers designed to withstand elevated temperatures

Prefer high-solids for rust prevention

High-solids formulations create thicker films that better seal and inhibit rust on bare or treated metal

Select appropriate application type

Use spray primers for even coverage on complex parts and paste or brushable coatings for seams and underbody areas
