The centerboard trunk in my Sandpiper (15' Marshall Cat) has an uneven "wavy" surface. It's not rough like an Thomas English Muffin with sharp peaks, nooks, & crannies, but rough with softer highs and lows as if the surface were laid on by hand and not troweled smooth.

Here are some pix of both sides

The lower pic is after considerable sanding with 60 grit loaded onto my 1/2 sheet finish sander plus a lot of hand sanding. There are still some glossy low points.

The top pic was soon after I realized I need some suggestions as to how to abrade the low points to guarantee good adhesion.

As much as I would prefer a perfect smooth surface, I think that ship sailed long ago.

NO, I do not have access to a bead (or sand) blaster.

I do have course scrub pads, wire brushes (both hand and drill driven), sand paper, etc. I can always get some bronze wool. I could fetch some beach sand and impregnate a scrub pad with it. If anyone thinks those ideas would work.

Yes I could strip, and prolly should have at the beginning, but now my stubbornness is getting the better of me <grin> Also, I am not adverse to smoothing out the surface a tad.

I am open to all ideas, proved or theoretical.

And yes, I have considered sheathing the trunk in teak . . . . .

You should keep all this in the other thread, it makes it much easier to follow.
