Evercoat Super Build 4:1 Polyester Primer Surfacer

Evercoat Super Build 4:1 is a premium, two-component hybrid polyester-epoxy primer surfacer engineered for automotive refinishers who demand superior filling power, exceptional adhesion, and long-term durability. Designed with Evercoat’s patented 4:1 mix ratio technology, Super Build 4:1 delivers industry-leading build capabilities in fewer coats, making it ideal for leveling rough, uneven, or highly repaired surfaces.

This VOC-compliant, high-solids polyester primer passes 500 hours in ASTM B117 salt spray testing, ensuring outstanding corrosion resistance and long-lasting protection. Its advanced formula bonds exceptionally well to fiberglass, SMC, rigid plastics, aluminum, body filler, putty, and even properly prepared bare metal—without requiring an epoxy pre-coat when applied at proper thickness.

Whether you’re restoring a classic car, repairing collision damage, or prepping custom panels, Super Build 4:1 creates a stable, smooth foundation compatible with waterborne and solvent-based systems.
