Tarr and Augustus Wonson established Tarr & Wonson, in and experimented with creating a paint that would protect the bottoms of wooden boats, ultimately settling on a mixture containing copper. The company's copper paint, as an advertisement stated, was "a perfect substitute for metal sheathing for one year, effectually protecting the bottom from boring of worms, and the adhesion of barnacles, grass, seaweed, moss, etc." Preventing marine growth reduced the travel times of boats, thereby resulting in a savings of time and money.
