I went to countersink the #6 holes in the wing tip edge to accept the dimpled edge of wing skin for attachment with #6 screws.
The white gel coat cracks/splinters off well outside of the circumference of the countersink. Is there a trick to get good clean countersink for these holes? Funny that I did not have this problem when countersinking for my platenut attach rivets but these #6 holes are little ragged around the edge.
