General Maintenance
Ensure that you cover your boat when not in use. Wash the entire surface with a soft rag or sponge and a mild detergent at least once a month.
Seasonal Maintenance
About every six months (after completing your normal maintenance) wax the surface with a carnuba-type paste wax. Avoid using any "abrasive" cleaner-type waxes as they will actually remove your protective surface. Mechanical buffing is not necessary, but may help to speed up this step and leave you with a deeper shine.
