Great for getting the non-skid sections clean. Pour a little bit of cleaner on the deck and scrub away, this will clean up a lot of tough black spots and dirt. You can use laquer thinner on hard fiberglass surfaces, but be careful not to get any lacquer thinner on the windows though, it will melt them! Wash the boat after using the laquer thinner and use gloves. Best to have a clean rag nearby.
Chemically resistant bristles. Molded plastic block with comfortable finger indent handle. Medium bristles for general cleaning.
