Can Coated Sinkers Be Used in Pressure-Treated Wood?

Yes.

Pressure-treated wood is typically coated with a variety of chemicals, including chromated copper arsenate (CCA), to protect it from rot and insects. While CCA can be toxic to some organisms, it is not harmful to can coated sinkers. Can coated sinkers are made of a corrosion-resistant material, such as galvanized steel or aluminum, that will not react with the chemicals in the pressure-treated wood.
