I just bought a gallon, I will keep you all posted on how clean my micron csc bottom stays. I am applying it July 21. This product is non toxic water based, originaly for used in the medical industry as tool lubricant inside your body so it safe to say it safe for the environment. It will reduce fuel consumption by making it hard for marine growth to attach to your hull. When we are sailing in light air, the friction between the hull and water is greatly reduced. Bare hulls need to have tooth for this to stick, use interprotect or preferably a petitt hard antifouling as a base cost, then apply sea slide.
