Koch Chemie Marine Protective Sealant Spray for Gelcoat | Fort Myers

Marine Protective Sealant is Koch Chemie’s efficient spray sealant for high-gloss gelcoat and boat paint protection. After pre-clean and polish, Fort Myers detailers use it for a transparent, uniform finish with color deepening and strong hydrophobicity—protection lasting up to about half a season depending on use and conditions.

Features / Why Pros Use It

• Spray sealant for gelcoat and boat paint—simple, high-gloss protection
• 100% transparent finish with color deepening and hydrophobicity
• Protection up to roughly half a season (use, care, and climate dependent)
• Apply after Hull PreCleaners and gelcoat polishing / degreasing as needed

How to Use

• Pre-clean with Hull PreCleaners; polish oxidized gelcoat as needed
• Degrease the surface before sealing
• Spray onto a towel/applicator—do not spray directly onto gelcoat/paint (slip risk)
• Wipe evenly; avoid hot surfaces
