Just primed my bottom for anti-fouling. When I took off the masking tape, I uncovered a hole (12mm x 4mm) on the surface. To me it looks as if there was a bubble in the resin during manufacture which has now decided to show itself. There is no indication of a repair but I can see the fibreglass matting underneath.
As it is above the waterline, can I just fill it and use it as an excuse to re-paint the hull.
