Review on Industrial Strength Aluminum Foil Tape - 4 Inch By 210 Feet - Ideal For HVAC, Metal Repair And Insulation! by Matt Eason

I recently constructed a Faraday Cage from a metal 5-gallon pail and metal lid. In order for it to work correctly, I needed to ensure that there was a metal to metal connection on all seams of the pail and lid and this roll of aluminum foil tape did the trick! I highly recommend this tape for any project where you need to join several electromagnetic conducting surfaces together.
