OK for lack of a better way of describing it, I guess it is delaminating on the outer wall of the slot in a turn. I think it might be caused when a car spins out and the guide goes full lock. Most of the time the car flips, crashes out of the track, pretty violent crash. These are Sprints plus, H&R, homemade. Heavy fast cars. Same cars I used on my last oval that had a Gazillion laps on it and never did I see this happen. Any of you ever experience this.
