A high-build two-part epoxy primer that dries fast, enabling application of a complete barrier system and bottom paint in just two days. Extremely effective for blister prevention on fiberglass, or as a bilge coating, because it is resistant to oil and water. It can be used as a universal primer for corrosion protection on most metals below the waterline such as props, keels, trim tabs, thru hulls and lower units or for priming any metal. Fills deep scratches and gouges in a few coats.Not for sale in California.
