You can use a graphite charge ring as well.

ESL Diaphragm coating

I have been using aluminium tape and I never had a problem with my panels of 9 years old, You just scuff it up real good with some steel wool and your good.

I use this computer screen cleaning gel for coating the diaphragm on my electrostatic headphones and it works great.

I'm sure you can find something similar there too.

Thanks, I found couple antistatic gels for LCD screens, might test them.

How thick and untransparent is the layer of licron crystal when applied undiluted with a sponge? I found a local source, but would have to pay ~65 dollars for one bottle. That's quite much but if the stuff is good, then it's worth it.

CharlieM once told that it was only a few microns thick.
I can't seem to get a reliable reading using only my micrometer.
I can with the regular formula Licron.
It is pretty transparent otherwise yet only very slightly cloudy, But it is hardly noticeable when looking at it through the stators.

It's correct that Audiostatic used copper foil tape, but it's unnecessary for transmitting low current high voltage. You could use for example the tape used on windows for burglar alarm systems.

A tip to check if you have high voltage leakage: Disconnect the high voltage PSU from the outlet... If you speakers can continue to play for several minutes without a volume drop then you know your high voltage part including membrane coating is okay.

All you need is to find microscope, make the cut through the coated tape at 45 degree angle and have a look at the cut. You will see the thickness of the coating it terms of substrate thickness.

^Thaks for the tip.

Licron crystal is ordered. I found the local distributor (in Finland) via "find distributor" application on the Techspray's website, bottom right corner: TECHSPRAY

The Licron Cyrystal comes in an aerosol spray can. One wet spray coat looks thick initially but it's 98% solvents so it dries to about 2 microns. I can't say how thick it would be if applied with a sponge.
