Y-10 fiberglass cleaner

Y10 removes discoloration in the waterline and around the exhaust, stains on and around fittings and plant stains. Also excellent for cleaning non-bottom treated plastic boats. Apply the gel, watch the discoloration disappear and rinse with water. Attaches and works in all situations, even when the boat is in the lake. 500 ml is enough for a 30 ft boat about 3 times. 0.5l
