Hi Ari,
Have you checked that these alternatives with aerosol formulations are suitable and have you tested these products?
You have not provided any commentary on what and how?
The product used by Jbl on compression driver diaphragms is a diluted water based compound and applied with a spray application in very thin coatings?
It’s not a thick paste.
Some members used a fine art brush and a rotatable table like a turntable platter and applied two or three very light coatings. Bare in mind the jbl used lighter titanium diaphragms in some instances.
I recommend you experiment on aluminium foil.
Ian, I have not tried any of this stuff, the reason I did open this thread was to find any member that know something about this stuff
I did talk to Guido in Germany for few week´s ago and he point me on this stuff, and he did use this coating paint

about the thin layer, some of this stuff I have mentioned are used with water to get light coating
does people here really think at JBL let us have the formula for the Aquaplas paint coating paint they use for there drivers and diaphragms
we need to try some of this stuff like a sample first before we can say at this is the right stuff
I do believe it’s a commercial product and yes some of it was passed around.
I did in fact observe Rich paint a diaphragm.
It was a privilege to observe a true artist doing what he does best.
I being the tourist was charged with topping up the wine glasses during the procedure.
My inclination is less is more with these coatings.
Good luck with your experiments and let us know how it goes.
Btw l will be in the UK in Sept/Oct. Perhaps an opportunity will lend itself to reunion.
I realize this tread are few months old.
But I suggest experimenting with the Noisekiller products.
its a water based viscoelastic damping compound aviable in 1L cans.
I have used it at the backside on paper cones for adding mass and stiffness with good results.
And believe it should be possible to use it on metal diaphragms too, if thinned properly (with water)
Back in the days there was a version sold by Rockford Fosgate with a pretty grainy almost "sandy" consistence.
But the Noisekiller black. I bougt last time where much smooter, almost glossy.

The Speaker Exchange has a white coating recone for the 2213/123a...wonder what it really is made of?
