Where does one find the 4 x 8 sheets of 60 mil the article referenced?  I
know the local Home Depot yields up the aluminum flashing by the roll, 
but I
don't think it sells the 60 mil (or, 30 mil which could be doubled up to cut
down the possibility of flashthrough due to a weak spot in the poly).  Also,
where does one buy mineral oil in 5 gallon lots?  I am a pretty good
procurer but have no clue in this area.
Look in the Yellow Pages under "Plastics" for the poly, "Petroleum" or "Oil"
for the oil.  The oil dealers will have the genuine transformer oil which
has been specially formulated for HV work.
