Now when I was building guitars under the Von Herndon name. I shielded 25 guitars in less than 2 weeks. I ran out of copper tape and nobody had it locally. Some people advocate using the snail copper tape, but I have found that when you apply it in sections, the adhesive is not conductive and the individual pieces do not have full continuity. I found a solution at the Dollar Store while looking for some craft supplies for my Son's diorama school project.
They sell a 2" wide aluminum tape for $1.00 a roll. It's much thinner than copper, but it worked well and gave full continuity. I still prefer copper, but this is a locally obtainable solution when a project must be completed and you cannot wait for resupply. I have applied copper over aluminum and aluminum over copper with excellent continuity.
Many times, I will shield the cavity cover plates with aluminum, just to save on the copper tape.
