Buying Guide

Match coating to application

Choose engine enamels and heat-resistant primers for high-temperature areas and rust-seal or metal coatings for chassis, seams, and exposed metal

Check formulation and compatibility

Confirm whether a product is urethane, enamel, or high-solids and pair it with compatible reducers like LAUCO urethane reducer to ensure proper flow and adhesion

Prioritize corrosion prevention

For long-term protection use rust-preventive products such as KBS RustSeal or water-free pastes that inhibit corrosion on wheel wells and tire-contact areas

Review coverage and container size

Select product volumes that match project scale—small pint or 11 oz packs for touch-ups and multi-gallon reducers or pastes for larger repaint jobs
