Bummer. Chukar has developed a rather nasty rash of tiny blisters over just the past summer. They concentrate at the water line more or less, run a foot to two along a lapstrake then die out then start again, and range in size from and eight or a quarter inch in diameter (so they do not seem surgically removable like big blisters are...). Any other M15 owners encountered these, and if so, any plan to do anything about them? tom
