Re: What is your latest primer of choice? Below waterline...
We use red lead by the gallon where appropriate. But my high tech go-to primer for superior adhesion and working qualities for the fine work is the System 3 waterborne emulsion epoxy yacht primer. It sprays or rolls great, sands out excellently, and works as a tie-coat for all sorts of different top coats over just about any surface. That's the yacht-grade stuff. You can use regular red lead for below the waterline on old workboat repairs though.
Amphibious Macroplankton Oughtredia doublendus
Mostly found frequenting the littoral and estuarine zones in the southern half of the Salish Sea, though sightings have been recorded both north and south of this area, and occasionally, but rarely, inland, in freshwater environments. This species lives on micro-brewed beer and dutch-oven biscuits,and displays brightly colored nylon and gore-tex plumage during the rainy season. Approach with caution!
