Grayson,

I have built a couple of small caps using this poly (5 sheets of 6 mil, 30
mil total). They work just fine at 5000 volts, but not 7000 volts. From now
on I'll probably use the "good" stuff for big jobs. I can get 60 mil 4x8
foot sheets for $18.50. That seems pretty reasonable. By the way, it is
polyethylene.

Good luck on cap building,

    Adam
