Wax Solution – Mod C (Surface Seal Additive)

Wax Solution Mod C is a professional surface cure additive designed for use with polyester and vinyl ester resins or gelcoats. By rising to the surface during cure, it forms an air-blocking wax film that allows the resin to harden completely without surface tack.

Key Benefits

• Eliminates tacky surfaces caused by air inhibition
• Produces a smooth, hard surface ideal for sanding, painting, or polishing
• Essential for surfboard hot coats, ensuring a clean cure before sanding
• Compatible with polyester resin, vinyl ester resin, and gelcoats

Usage

• Typical addition: 1 oz per quart of resin or gelcoat
• Mix thoroughly before applying
• Use only on final coats or hot coats – not for laminating layers to be recoated

Whether finishing a fiberglass layup, sealing a gelcoat surface, or applying a hot coat on a surfboard, Wax Solution Mod C ensures a complete, tack-free cure and a professional finish. It’s a must-have additive for marine, composite, and surfboard building applications.
