The Faramount works, but it must be heated before coverglass application, 
and the heating adds another step you have to deal with, Howevere, it is 
very nice aqueous media that sets up hard and clear.

We have also done frozen sections with DAB and set up the 
dehydration/clearing for permanent mounting media.  I must admit this gives 
a superb final preparation that when dry, the mounting media doesn't 
retract under the coverglass.  It is not that difficult to set up the 
dehyration/clearing/permanent mountant,  and there are some nice 
mini-staining devices to help you out depending on how many slides you 
stain at one time.   We prefer dehydration/clearing/and permanent media 
with DAB.
