I used Pettit zinc spray and found it did little to stop barnacle growth after a year. Last haul out I reapplied the zinc spray after sanding down to bronze (Campbell Sailor fixed 3 blade), and then brushed two coats of Pettit Horizons ablative paint, but I won't know if this is better until next year. The Horizons was quite effective against hard growth on the hull after 2 years in BC waters, with only a line of green slime at the waterline.
