I have a 2013 225 Ultra with Steel Blue gelcoat. After occuring minor scratches in 2014, I used mild rubing compound to work them out, followled by marine wax. I noticed in some areas that numerous whites dots the size of pinheads appeared. The dots were not pinholes as if air pocket but were flish with the rest of the gelcoat. The only thing I could think of was the color gelcoat was way too thin and I had gone down through it, but I was in disbelief because the scratches were very minor and all 4 previous boats I have owned used to get rubbed out every year. In the 2015 season I chipped the gelcoat down to the fiberglass on the corner of a dock(bumper was missing but nails were not). I took the boat to a professional gelcoat repair company and when they were done the area matched perfectly, EXCEPT a ring around the rapair had hundreds of white dots. They too were puzled, and speculated that the boat started out white then was changed to steel blue, or the steel blue color was too thin. has anyone seen this before, or have any insight?
