If you put coppr foil or tape uner the pots, it will be earthed by the pots surely, so theres no need to solder to it.
As for slugs, I tried wire and it didnt work, even tried putting a slug inside a circle of it, but it still got out. This year I,ll be trying 2 wires half an inch apart with an aa battey connected between. anybody tried that one ?

Shorting the batter with copper wire will run it out fairly quickly, need a resistor involved. Also its the joints between the copper pieces that need soldering, just in enough places its all connected, don't need to do whole seams.
