Fiberlay Surface Seal is a wax‑containing surfacing agent designed to eliminate air inhibition on the surface of curing polyester gelcoat and laminating resin. When added to the final coat, the wax migrates to the surface as the material gels, forming a barrier that prevents oxygen from interfering with cure. The result is a hard, fully cured, tack‑free finish ready for polishing or light finishing without additional sanding for cosmetic jobs.
