Always buy the best you can afford. bottom paint with the highest copper content is your best bet. ...one other thing , if your getting alot of growth on your bottom , your not useing the boat enough......one more thing , if you don't like sanding the bottom try ...WIL_BOND...your local hardware store should have it. cuts through old layers of paint so the new paint will stick. been useing it for years....NO MORE SANDING...
