  • Just use Drywall mud as an insulator.
    I was doing drywall work today and have dried taping mud on my pants. I also have a dmm sitting beside me. I put the two together and found no conductivity down to about 1/64" - 1/32" thickness. Throw a layer of mud between the connections and you are set. You also might want to seal the mud with a paint primer before you paint again to ensure the latex does not seep through the mud to the other connection.
    You could also use electrical tape, and mud over it to hide the tape edge; but you cannot use tape alone. The latex paint will not stick to the tape, or any rubber based insulators mentioned here, without a primer.

No public wish lists :(
