Seasonal Maintenance


Proper preparation is required for anti-fouling the hull of a boat, especially the first time it is applied to maintain the manufacturers’ warranties and to insure the coatings have the best possible bond.

Applying antifouling on or near aluminum requires knowledge and attention to details. Done improperly, once can create serious damage to the aluminum hull surface. Best to consult a professional to ensure proper product choices are made and steps are followed.
