Polylester Gelcoat Polishing Process

Polyester gelcoat is a widely adopted surface solution known for its cost-efficiency and versatility across marine, automotive, and composite applications. While offering good aesthetic and protective properties, it is generally more sensitive to environmental degradation compared to higher-performance resins.

Polishing polyester gelcoat involves removing oxidation and micro-defects while maintaining a uniform finish. Process control is critical, as excessive material removal can compromise the surface layer.
