I have a very small circular crack on the side of my hull, well above the water line. It is about the size of a dime. Its 12 oclock position is at a radius turn toward a horizontal surface near the bow seats. The circular crack is not complete it starts around 8 oclock and goes clockwise to about 4 oclock. It is hair line thickness only. When I push on in I can see no movement anywhere or any change in the cracks thickness. My questions is should I do something? Just keep it waxed well and keep an eye on it? Or try to seal it with something?
