Protecting Gelcoat & Surfaces During the Cold Season

Sustainable winter maintenance for your boat

Winter is one of the most critical phases for boat maintenance.
Cold temperatures, humidity, salt deposits and atmospheric agents continuously affect gelcoat, rubber and exterior surfaces, leading to oxidation, dullness and residue buildup along the waterline.

When the boat is moored or stored, salt deposits remain longer and moisture penetrates the micro-pores of the gelcoat, accelerating deterioration.

The hidden risk: environmental impact

During winter, rain can wash chemical residues into marinas and basins.
Non-biodegradable substances, persistent silicones and microplastics accumulate in the marine ecosystem.

Choosing the right products makes the difference.
