Does black grate polish work as propeller antifouling? This reader finds out...
This prop came off a friend’s boat that had been in the water for four months, cruising the English Channel and Brittany. When it went in the water the clean and polished prop had been treated with Stovax Black Grate Polish. The result was not bad at all for a season which saw a lot of serious fouling, and the polish is super value at £4 for a 75ml tube.
