Primocon is an anti-corrosive one-part primer for underwater metal as well as non-metal surfaces including hulls, running gear, and the lower units of outboards and I/Os.
It provides a barrier to reduce pitting caused by galvanic corrosion. Suitable for use on aluminum, lead, steel, and cast iron.
Although somewhat less expensive and easier to apply, one-part Primacon is a step down from Interlux's premium two-part epoxy primer Interprotect 2000 for underwater/antifouling use, or Interlux 404/414 two-part epoxy primer for above the waterline use.
