Just in case you don't know,
The EPA has classified bottom paints as pesticides and registers them as such. Many are general use products, which means anyone can buy them and apply them to their own boat and on property that they own. Some, such as TBT paints, are Restricted Use and the applicator must be certified with the DEC in order to apply them in NY state. TBT paints are used on aluminum. The only TBT products that are not Restricted Use come in a 16 ounce, or less, spray can. You can find bottom paints in many marine supply stores.
