I know from experience that a car will get some racing marks over time when raced, but when auto-crossing there should not be more than cone marks to remove.
My car was absolutely perfect before I started auto-crossing this year. I got the first damages from a piece of pavement on the east lot event, then last weekend I got a few more marks which can't be polished out as they are dings and scratched to the metal. I't's not the end of the world for me as I think Porsches are meant to be used. However, if this keeps up I may reconsider racing at the stadium.
I think we really need to emphasize the corner-workers to remove the chunks of pavement ASAP, if necessary call in for help or hold the track.
I agree it's time again to patch/repair the parking lot or start looking for an alternative location such as an airport or an industrial parking lot.
See attached pictures from the damages it caused (not cone marks !!!) to my car from the stadium.
