It appears that I have sanded to deep on the hull in my vigor to remove excess epoxy. I have open the first layer at the middle seam of the hull (1/8" in some places). I was using 80 grit for my first sanding on the hull.What can I do to fix this problem? I was thinking of epoxy fillet again or adding a strip of glass down the middle to minimize the problem. Although this is only on a small (1/8 ") layer along the middle seam. Any suggestions would be appreaciate.
