Hi: At the risk of having billard balls thrown at me, I can attest that bees will not rebuild comb that has been taken down to a slick plastic surface. I have examined thousands of commercial colonies and seen lots of frames with previous mouse damage. The bees never fix it. In fact, it looks like they polish the bare spot.
