Prepare the paint surface by pre-cleaning with our Hull PreCleaners. If necessary, polish the matted or chalked surface using our gelcoat polishes. Degrease the surface using Panel Preparation Spray. Apply four to five sprays of Marine Protective Sealant to a Polish & Sealing Towel and apply evenly crosswise to the surface to be sealed. Proceed in sections (approx. 1x1m). Then polish with a clean microfiber cloth. Do not allow to dry. The boat or watercraft must not be washed with chemicals on the same day. Afterwards, wash with a neutral shampoo during routine maintenance to ensure that the sealant lasts as long as possible.
