I have a 30 year boat that is badly oxidized and the gelcoat is quite thin in places and really ought to be painted however time didnt allow for that. I wet sanded the hull and used 3m restorer and wax on it and had decent results. My gelcoat is a dark color and there are areas where I can see microscopic yellowish pits. The entire transom is like this as well as other areas which I think are most prone to reflection off the water where the hull curves before it goes vertical.. I was told that this is a sign of moisture in the fibreglass which apperently can lead to delamination. I thought it was just heavier areas of oxidation. I am hoping for some opinions and guidance that may help me decide what I should do about it, or how to confirm the problem either way.
Thanks in advance
