I've been trying to track down a source conductive spray paint. A rep from a
electronics co. said that such stuff has been banned for sale by the EPA. He
sounded convincing to me.

Is this kind of a product legally available in the US. I'd like to know?

Click on "Products", then on "Conductive Coating". Their MS-487N is a
nickel-based conductive paint, intended for RFI/EMI shielding.
Will attack acrylic, polycarbonate, polystyrene plastics. It's
available as a liquid but not as an aerosol. You might be able to use
it in a commercial airless paint sprayer.

Less formal solutions to the problem, which I have seen suggested but
have not actually tested myself, include:

- Carbon-based black spraypaint intended for high-temperature
applications such as woodstoves, stovepipes, etc.

- Zinc-based "cold galvanizing" spraypaint.

I have no idea what sort of attenuation you'd get from either of
these, or what sort of surface preparation, priming, or overcoating
might be required on various materials.
