I'm sure I was getting close to crazy fitting some of the tape around
the boxes, but your post was nice to keep in mind. I have no regrets
about filling all the screw holes in the electrical boxes with 6-32
screws before I started spackling near the (plastic) screw holes. $2 is
a minuscule price to pay for the peace of mind, and I'll reclaim the
screws. A Q-tip came in handy too.
