My car's fuel filler door often freezes shut in winter, and I can't put gas in because I can't get it open. The problem is caused by the orientation of the opening. The rectangular door is oriented with the upper and lower flat parts on the level. A film of water builds up in the lower gap, and when it gets cold outside, that film turns to ice, gluing the door shut.
simple solution: change the angle of the opening so the water runs down to the corner nearest the hinge area, where leverage is greatest.
