One possibility is to paint narrow line of a dark contrasting color around both the galley hatch, the galley opening edges and the galley gutter. To get the idea of what I talking about turn to page 288 of the manual where they put a thin strip of vinyl tape on top of the eyebrow seam.
I don’t think the vinyl tape would be up to the rigors of the wear and tear the galley hatch is going to get. I’m going to use a black semigloss or satin polyurethane, which will tend to visually hide any irregularities along the hatch edges. I plan to do the same with the cabin doors. The black non gloss paint will blend in with the black gaskets and foam seals.
I’m finishing my TD with off white polyurethanes, but I think black edges around the hatch and doors would look especially nice with the bright (sailor talk for a clear finish) and black accents shown in the manual and online.
