303 Marine Touchless Sealant – 128oz (30399)

Achieve a high-gloss, water-repellent finish with minimal effort using the 303 Marine Touchless Sealant. Designed for boaters who want professional-grade results without the hassle, this spray-on, rinse-off marine sealant delivers powerful protection and shine in minutes—no rubbing, buffing, or wiping required.

Perfect for use on gelcoat, fiberglass, paint, glass, and more, this advanced formula creates a durable protective barrier that repels water, dirt, salt, and UV damage, helping keep your boat cleaner and looking newer for longer.

Core Technology & Performance

• Hydrophobic Water Beading: The silica-infused formula creates a surface tension that causes water to bead up and roll off immediately, taking salt, dirt, and grime with it.

• Touchless Application: This is a "spray on, rinse off" product. It activates upon contact with water, meaning you can treat an entire boat hull or deck in minutes while it is still wet from a wash.

• UV & Chemical Resistance: It provides a durable barrier against UV rays that cause gelcoat oxidation and protects against bird droppings and fuel spills.

• Versatile Surface Use: It is safe and effective on gelcoat, paint, glass, plastic, and even metal fixtures, providing a consistent shine across all exterior boat materials.
