paint it you will loose some but not much.
And if you don't already know the solid refractory is going to crack, its designed to crack, one reason manufactures recommend that the minimum pour/cast thickness be 1.5 inches. The cracks are there to relieve stress in the refractory as it heats up and cools. So when you look in it an see little tiny cracks don't worry its not going to fall apart, and you don't have to try to patch them like some do.
