Not much help to you I'm afraid as I can not recall product name but I have used with satisfactory results, for the past 7-8 years, a two can spray - undercoat gold, top coat black - cost +/- $16 a can. Try checking West Marine who I think may stock it.
Another vote for Trilux. Used it for 7 years, antifouling performance on the leg / prop doesn't seem any worse than with the copper based stuff used on the rest of the hull, and little sign of corrosion.
