Mike,

The same thing happened to me on my first boat, a Pygmy Osprey. To fix it I cut a rectangle of fiberglass so that it covered the bare spot and extended into good fiberglass by about 2 inches. I then epoxied that piece over the bare spot and filled the weave with a second coat. I let the patch stand for about a 2 weeks while I did other work on the boat. After the epoxy was cured I hand sanded the edges of the patch so it feathered into the surrounding surface.

Today there is a little bit of a bump that you can feel with your hand (if you know where to feel for it). But you can’t see the patch at all.

: Hi Folks,

: Need some advice.

: I have started sanding my coho in prep for varnishing. This was my first boat
: and it is full of drips and runs and the thickness of the epoxy varies
: from place to place. I am working for as flat a surface as I can get
: without cutting through the glass. However,... there are 4 spots where I
: have cut through to bare wood while working too hard on some drips. 3 are
: minor but one is about 8 inches long on a seam in the hull. It is about a
: foot away from the stern stem so should be a low stress area.

: Question, what to do about the cut through spots. Epoxy saturate sand and
: move ahead with varnish or patch the spots with glass and try to blend it
: in?

: Thanks in advance for the help
