Electrical conductivity is just one part of getting the ions neutralized.
Also plastic, glass, Teflon will be effected.
It all depends to their distance between positively charged or negatively.
The wider on the list, the more PITA.

With my pad under the tumbler or stainless cup, I am not seeing any noticeable difference in static - but I use two drops RDT, so that trumps all! I have gotten in the RDT habit since it works so well... if it ain't broke....

BTW, I have gotten a little more out of Scott's earlier rec of washing the funnel with soap and water (might have been in another thread) - can't explain it - but it gave that extra 10% push and seems to get the final cling-ons...

This looks pretty now, until it starts oxidizing.

You would have to get it to near mirror finish, then constantly polish it.
Not to mention every time you touch it the oil in your hands will corrode it.
If not wiped off potential for permanent finger prints.

If the equipment grounding hardware does not pierce this anodized coating, the technician needs to manually remove the anodization at the equipment ground locations. Otherwise, the anodized coating gets in the way of an electrical bond.

Perhaps the "shiny ring" that weebit_nutty reports under the blind tumbler is inadvertently removed anodization resulting in higher conductivity than you'd normally see with anodized parts.

Craig said he planned to clear it after the polish.

I am beginning to think it's not continuity that's the problem but air flow that dictates the dynamics of the charged ion particles. Most antistatic systems in industry use air pressure to blow negatively charged ions to neutralize static problem areas.

This can be tested by masking only the contact area of the metal tumbler and see what happens...

BTW on the standard HG One, what would you call the raw a AL areas texture? Bead blasted?
