That is normal for the green foam used on the KR-2, it sands super easy, it is brittle and it should be fine.
The only thing that will cause it to deteriorate is if it has been left out in the direct sunlight, which will cause it to change color. The strength is in the fiberglass, the foam just creates a form to shape the layups, it adds little to the structural strength overall. Hope it helps.
