Koch Chemie Marine Protective Sealant
Koch Chemie Marine Protective Sealant Spray for Gelcoat | Charleston, SC
Marine Protective Sealant is Koch Chemie’s efficient spray sealant for high-gloss gelcoat and boat paint protection. After pre-clean and polish, Charleston 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
