And silver PCB repair paint is more expensive than it sounds! I painted it on once with a pin from an IC to a SMT miniature connector.
I've occasionally wrapped Aluminium foil earthed via a spring to a neighbouring IFT. There was conductive nickel spray 30 years ago for EMC shielding of plastic cabinets. I bought it once only because it was so expensive and after that used glued on aluminium foil on cases, sometimes with a paper clip for the earth wire if a screw and tag wasn't possible.
