The interior teak finish throughout my 2000 H340 still looks great except for around the galley sink and refrigerator top. Years of sun, handling and water have started to fade the finish. We apply lemon oil every other year to the interior cabinetry and everything looks good except the edging (fiddles) in the galley. I was thinking of applying some oil-based teak stain to try to bring back some of the color. Teak stain is getting harder to find, as West Marine, Home Depot and Lowe's don't carry it.
