I noticed small white scratches on the surface of my Guillemont while I was applying the second coat. I had sanded the runs and fiberglass strings out of the surface before applying the second coat, and I was wondering what caused this, and how it could be fixed. I suspect I sanded too far into the cloth. How can I cure this without going to the trouble and work of sanding the cloth off and re applying, it is a rather large area of the hull. Also, when finishing, what is the best way to finish eleminate the textured surface of the fiberglass cloth? Repeated coats of epoxy while sanding between coats?
