Sea Hawk Shawkocon is a fast-drying, general-purpose below-the-waterline anti-corrosive primer. Its physical properties and excellent adhesion characteristics provide an easy-to-use multi-functional primer: - Conversion/Sealer coating over Sea Hawk Biocop TBT 1200 Series antifouling or any unknown well-adhered antifouling paint to prevent cracking and promote adhesion of a new antifouling paint - Barrier/Sealer coating over incompatible or unknown antifoulants to prevent leaching - An excellent barrier coat to reduce pitting of underwater metals from galvanic corrosion on running gear, lower units of outboards, keels, pontoons, and I/O s - Prevents bleeding of color from underlying antifouling paint
