Obvious observations. Shielding effectiveness depends on the paint conductivity after applied and dried. The solid content by volume needs to be that which achieves the desired cured/dried conductivity.
Next, the surface conductivity will facilitate some degree of shielding effectiveness. But you didn¹t state the goal. If one coat doesn¹t deliver the required conductivity, then maybe multiple coats might, but whether that is practical totally depends on the ratio of single coat SE to desired SE. And finally, chamber SE is high-side bounded by the SE calculable from the paint conductivity. All seams, apertures, and penetrations must be handled in a manner to protect the SE inherent in the paint conductivity.

Obviously all the normal rules apply for ensuring a contiguous bond - I have only a limited idea on the difficulties that requirement will entail! FYI, the "spec" does not specify % by volume of the solid content. I am guessing that 50-70% by volume should be sufficient - does that make sense?
