Consider it baptized now, that first mark takes the stress away of trying to keep it pristine, which is a lost cause anyway.
I did it on my kapex as well, but the worst was cutting into my 1 week old Felder slider. A piece of wood jammed between the fence and blade and pushed the blade against the slider and made a notch. I guess it was bound to happen, i think it's worse if it happened after managing to keep it pristine for several years. that would have been a bigger bummer.
