Hull White Fibreglass and gelcoat cleaner.

Hull White quickly and easily removes waterline and transom stains on white or light coloured gelcoat.

Using a brush, apply a thin coat of Hull White over the stained area, wait approximately 10 minutes, then wash it off.

The gel formula spreads easily and adheres to vertical and overhead surfaces. Y10 is also effective against rust stains around A-frames and hull fittings.
