Dr. R,

Thanks for the information.  I'll have to score some Glyptal somewhere.
Out of ignorance and superstition I always expoy in a pair of lexan baffles
near the top and bottom of the PVC coil form shortly after drying.  This
being the case, is an internal coating still recommended to prevent
tracking?  What about the baffles?  Is this needless overkill?  I recall
reading several threads in this list which imply that the electrostatic
field created by the top load precludes any chance of arcing down the
center of the coil.  What's the straight dope?

Regards,
Dave
