In theory wet mounting would have the advantage that scratches in the 
film and most dust particles become almost invisible, because their 
refractive index is close to that of the mounting oil. The glass 
plates should be so thick that the outside of the glass is 
sufficiently out of focus. A good mounting oil evaporates reasonably 
fast and leaves no residu.
