Im sure I read somewhere that the drift days at Oulton make a hell of a mess of the bodywork with gravel flicking up?
IMO, the taster / novice days are great, because you are on track with people in the same boat as you, and you aren't constantly looking in the rear view mirror for stripped out race cars flying up behind you! Also, c.25 mins is enough for someone having their first go, as well as not being too tough on the car
