3 watt resistors??

Yup, theyre long enough to have a useful voltage rating

Hmmmm.....And what grade of polystyrene would that be?

any grade, its not specced for electrical insulation

I'm sure you know exactly what you're doing, though.

I included a ground shield in the styrene so that if it fails for any reason it arcs to ground, not to the user. And naturally HV kit needs testing before use.
