Hi Peter! I've had some experience in both repotting neon sign 
transformers and in using parrafin as an insulating compound.
The problem with using paraffin to repot a neon sign transformer
is it tends to shrink A LOT on cooling! I have found that by adding 
some mineral oil to the paraffin while it is still in a liquid state
will minimize this. In the long run though I have found it best to 
build a plexiglass case for the neon sign transformer and fill it 
with mineral oil. The mineral oil being a liquid will fill the 
internal voids much better than paraffin and also being a liquid, if 
breakdown should occur it is self healing.
