Hi Dmitry,

Almost all black dyes and pigments are at least partially carbon based and so will be a weak point for tracking of HV on the surface. Most plastic pipe salesmen don't know diddley about HV RF applications as even big conduit doesn't carry over 500 V @ 50-60 Hz unless it's custom made. Until you can afford another secondary on short notice, better to play it safe and stay away from black.
