Fiberglass Bottomkote® ACT with Irgarol® contains cuprous oxide and Irgarol®. The Irgarol® works to control weed, slime and algae fouling while the cuprous oxide works to control shell fouling such as barnacles and zebra mussels. This keeps the bottom of your boat cleaner for longer. It provides excellent protection against all forms of marine fouling in waters with moderate to heavy fouling and can be used in fresh, salt and brackish water.
