fixed their wagon by bending a copper wire around the pot about halfway up. Slugs cannot crawl across a copper wire due to a chemical reaction with the slugs body slime.

That's awsome! How'd you figure that one out?
I wonder if the Marine Antifouling paint (which has copper sulfate or sulfite... pretty sure it's sulfate) I intend to use on my raised garden will have the same effect. Perhaps a couple wraps of perferated copper tube fastened around the upper edge spraying inward for irrigation as apposed to burried vinyl would be the just thing to keep the snails and slugs far from my eatables.

(maybe even the bunnies too)
