Even with maintenance coats in the tropics, the Cetol on the caprail was shot. The same applied to the varnish in the cockpit, Equatorial sun is brutal. interestingly, the paint on the eyebrows and grab rails was fine (Pettit Easypoxy “Brightwork Brown”). We removed the varnish and Cetol with a heat gun. The only hard part about that was working around all the fittings and deckwork on or near the caprail. The heat gun leaves a very clean surface with only light sanding necessary before re-coating.
