This would be my best guess for catalyzed varnish although you may end up doing the entire bulkhead(s) to get a homogenous finish. Start out working in an inconspicuous area to see how it's going to look.Benteteau recommends using a water based compound / polish, Aqua Buff 2000, from Hawkeye Products for polishing out light scratches and dull spots
I'm confused!Count me out. I can only deal with teak. Looks like the finish is catalyzed varnish and yet other here speak of oiling the surface which is incompatible with varnished surfaces. Who knows ?
