Ask me about shaving naked!
You can also use automotive lacquer putty to fill imperfections though it’s too thick for small cracks. Doesn’t absorb water and doesn’t seem to interfere with honing. I’ve seen this putty on used stones coming out of Japan.
I’ve also seen Bondo used, but not on the honing surface, usually reinforcing ragged corners and sealed with something as Bondo will absorb water.
