Ah-hem! (Clearing throat.) Some moron put a bronze cutlass bearing on mine which created a sea of pinholes on that side. (The port side is fine.)
You need to clean out the pinholes somehow, then go through the usual etch/ epoxy/ prime / AF paint routine. As the epoxy thickens in the pot, you can keep dabbing it on to fill up the pinholes.
