Thats what I was told about this board, apparently when Madd first came out with this board it had this seperation or delamination problem and they fixed it, it does not do anything mechanically bad with it, I think that is why they have the two color sidewalls for this board the red and the green, the red is the earlier models and the green the later. Please if anyone knows anything defenite about this chime in because I am not positive.
