Sand the PVC inside and outside. Then wipe down with alcohol. Avoid the
water and soap (may contain traces of a semiconductor --- bad at HV).
We have a PVC pipe mfgr in Madison, WI. One day, as I was picking up a
pickup load of PVC, I noted a worker filling a cup that feeds the extrusion
die. I asked him what it was. He said it is a special type of grease that
aids the PVC extrusion process.
I took a sample home and tested it with a small handheld TC, and guess what?
It's conductive. It leaves behind a "glossy" look on the surface of the
Sand this off inside and outside before sealing. It's only a small amount,
but why not spend the extra 5 min and do it right.
