I'm looking for that metallized spray 'shield' coating that I can use to coat the inside of a PVC enclosure - to protect the internals from local RF noise.
Grounding it to the local 0V rail - I suppose will be a bolt with star-washer for contact, and spade/QC terminal ?
I haven't tried this approach before, but I'm using a 3G cellular antenna about 2-3 inches away from a processor board and SLA battery. It seems I'm getting some RF leakage into the circuit (occasional restarts when the cellular modem 'lights up' for transmission - I guess those old-fashioned GSM burps and farts during a session).
Current testing has a sheet of heavy cooking foil (effectively a ground-plane) about 1/2 inch below the antenna between the enclosure and the processor board... seems to be significantly better - possibly fixed.
Any other suggestions.

To connect to it, bury/glue/attach a wire strand in the plastic in a few spots, then paint the shielding on. You could probably run this back to a screw on the case to attach your cct. This will be rock solid
