The crusted diamond dressing tools for dressing grinding stones actually work on TriZact Gator belts. Those belts tend to glaze over, so a couple seconds on the dressing tool helps unclog the belt. I tried the same tool on a ceramic belt and it made it smoother, but didn't cut any better. I try to find ceramic belts designed for grinding at lower pressures where the grain fractures easier. VSM is the brand I normally use.
