There are several types of ways that pickups are taped.
Gibson tapes each coil, then for uncovered pickups - they tape the two after they're mounted. You must undo this outer wrap to get covers on (usually, but not always).
Other places just wrap each coil. Others only wrap around the outer assembly.
If you have coils on, just leave it all in place and dunk the pickup. If you have covers off, use the rubber band trick.
