We use DPX extensively in our lab and actually make it ourself!  The
initial batch is quite thick, but can easily be thinned down with xylene to
whatever consistency you like (I prefer it thin, but the boss prefers it
thick)!  It is very easy to peel off the excess from around the coverslip
when dried.
