Miller-Stephenson Chemical Co. makes a product called MS-485 RFI Conductive
Coating. This is a spray which can be used on plastics as well as metals.
The spec sheet I have for it claims an attenuation range of 105 dB @ .150
MHz to 44 dB @ 1000 MHz for a 2 mil thickness.

My information is several years old, but may still be valid.
