I don't use them, but a few people on the list, in years past, have reported 
problems with them.  As Scott pointed out, the voltage reversal will kill 
them.  You need a Maxwell rated for 100% reversal.

We make our own now, conservatively rated at 80 kV DC with a Q factor 
greater than 20,000.  60 nF and 100 nF sizes available.
