On my 17LT, built in 2007, I now have two spots (each spot only 1" in diameter) on the hull where I can see the weave of the glass. It isn't super obvious and can only be seen if the boat is on the roof rack in bright sunlight.
I can't feel the glass. There is definitely epoxy over it and at least 6 coats or varnish.
Is it possible to sand down those spots and add more epoxy to cover the weave, then rebuild my finish layers?
