my A class did same thought of running a length of pvc tape where scratches were and replace when starting to wear through , it was in days of Ally masts so I wasn't unduly bothered and never got round to it , with a carbon mast would be more important , judicial filing i expect would help .
I think I also used to rotate mast slightly when pulling sail up to face hook away from mast , worked with A because of relative short foot (chord ?) length and sail would still pull up .
