"new" it's bright and shiny. as it ages it oxidizes and the oxide surface is a barrier to the galvanic action which is what 'tickles' slug/snail 'foot' into 'not going there.'
check with a local automotive body shop - they can point you to a supplier for....
the process is to 'degrease' the metal first, then the acid etch/wash will strip the oxides from the surface making it 'bright & shiny' again. then 2x fresh water rinse.
been there, done that
the downside is,,, it's a physical barrier, it's not 100% - perhaps 98.2% effective. a copper barrier does not eliminate/reduce/control the population.
catching/drowning them in beer, definite population control . . . .
