Black Trilux 33 Antifouling Aerosol - Interlux

I use Trilux 33 each year in late winter/early spring when I haul out for preventive maintenance. I use the Trilux 33 on the outdrive as needed. Since this is only January, I have not as yet hauled out, but I'm sure I'll be using the paint during late winter or early and it wil be as satisfactory as ever.
