The Original Fibreglass Stain Remover
Y-10 rapidly "absorbs" yellow/brown waterline and transom stains on white or light coloured fibreglass sailboats or powerboats
Brush a thin coating of Y-10 over the stain, wait approximately 10 minutes while a mild chemical reaction causes the stains to vanish then wash off. The gel spreads easily and adheres to vertical and overhead surfaces. Y-10 is also effective against rust stains around engine exhaust ports or other fittings and may be used on painted boats. Will not damage fibreglass Gelcoat.
Use in temperatures above 10 celsuis.
