How bad is cold weather on my Fiberglass boat. When I went outside this morning it was 19 degrees. That is just Too cold for me to fish. Left boat inside,and decided Not to fish today. Just wondering does this make it easier to get damage to the fiberglass if you bump something with it being this cold. Does the cold change the fiberglass molecules, so that it does not flex at all, or will it still flex a little, on bumping a stump.
