I found some nice trilobites in Utah last year and prep'ed them with an 
air abrasive tool using a mixture of compressed air and powdered dolomite.
This is the same kind of rig that is used to prep dinosaur bones and lots
of other fossils. 

If you have mucho matrix to go through, other tools(Dremel, etc.) are 
more efficient, but for the final prep and a nice clean, almost polished 
looking surface, the air abrasive is a great tool. However, access to one
of these may not be easy, I was lucky enough to have a local connection.
