Is polyester a good material for pulse capacitors?

If so then how about this for an idea on how to make a good cap.

Take a length of un-dyed polyester cloth and roll a cap with it.   Make the 
connections and house the thing in a good container.   Mix up a batch on 
polyester resin with MEK bassed hardener.   Not too much as you are looking
for a long curing time. Then vacuum impregnate the polyester cap with the
polyester resin.  Allow the resin to harden.

One nagging thought though.  Is mylar another name for polyester?

Any comments?
