The discussion centers on the feasibility of using acid to dissolve metals such as copper, aluminum, and nickel for creating a conductive coating on a rough plastic surface. Participants concluded that simply pouring dissolved metals in acid onto the surface would not yield a metal coating, as it would result in dry salts instead. A reducing agent is necessary to achieve metal deposition. Alternatives such as conductive pastes and epoxies, specifically 'Big Boy Filler' and 'All Metal', were recommended for effective conductivity.

refind said:I have a rough plastic surface that I need to make very conductive. I was thinking of coating it with metal but I do not know how. Would it be possible to dissolve some copper/aluminum/nickel (or others) in acid and then pour the acid on the surface and let it dry? Would that give me a metal coating?
The plastic is very resistant to acids.
refind said:Some kind of conductive epoxy could work, thanks for the pointer. The silver epoxy is ridiculous expensive, $43 for 16mL on Amazon :/
