Trilux 2 sucks. I can't think of any other way to say it. It is good for "maybe" one season, if that. There is no rejection of weeds and the barnacles and mussels (and last year, oysters) have no reticence to grow anywhere on the hull. Its crap, actually. I was thinking of using latex housepaint this year as the Trilux won't work any better and costs way more.
I can hardly wait for someone to invent a better, economical bottom coating which will put all these rip-off paint companies under.
Don't believe everything that you think.
