Dan, 

Although prepping the pvc will not help to give longer sparks, it might
perhaps make the form less likely to carbon track or burn up from
flashovers, etc., but I don't even know if it really helps in this regard.
Most reasonable secondary materials will give equal performance
for all practical purposes.  Of course you would not want to use a 
material that had conductive metal or particles in it, and the material
needs to be physically strong enough to support the winding and top
load, etc.
