Mariner centerboard overhaul

[Wayne Randolph]

After successfully dropping my Mariner centerboard, I had it sandblasted and primed (gratis) with a two part epoxy industrial paint called F-150. Unfortunately a brown cast is coming through in several spots where the primer either wasn't thick enough, or I didn't top coat it soon enough. I will probably have the job done again (and pay for it!). My questions are: What is an appropriate paint to use between the epoxy primer undercoat and the ablative bottom paint top coat? What difference will it make if it's protected, but unfaired?

Centerboard

Wayne -What is an appropriate paint to use between the epoxy primer undercoat and the ablative bottom paint top coat? - I would start by painting the blasted board with a metal prep product like Rustlock or similar, then coat with epoxy (not primer, the basic stuff). Next I'd coat with thickened epoxy or fairing compound, fair, and finally paint with ablative bottom paint.What difference will it make if it's protected, but unfaired? - You will point _a lot_ better with a fair centerboard. It doesn't seem like its going to make that much of a difference, but it truly does. You'll be pleased you did it.Justin - O'day Owners' Web
