I just removed some tt tips off/out of my transom...and glassed the holes in. Do I need to worry about the glass shrinking? I probably wouldn't ask but a season or so ago I glassed the back/top of my transom where a prior owner had butchered it. A couple months went by and I could see the pattern of the glass cloth projecting through my fresh white paint. I also removed/glassed 2 pop up cleats off the back of the boat a few months later.....in the right light I can see those patches now also. The cleat issue MAY be from primer shrinking.....don't think that's the case with the other repair though.
