This is the most effective way to shield your instruments pickup and control cavities, you just paint on 2 coats and it's done. With the cavity coated with the Shield Paint and connected to earth your wiring is in a shielded space and the interference that would be picked up by your wiring is sent to ground. This will significantly reduce hiss, hum and other noise from your signal.

What is in this Kit:

As it says, paint and only paint if you have a stick to stir it and a brush to paint it and some wire to connect it then this is all you need.  Still comes with instructions just in case.

This paint works really well to shield Strat and Tele type guitars as well as control cavities accessed from the back of guitars like those in Les Pauls and PRS etc where the wiring and controls can pick up interference. Gibson do shield some of their control cavities but it's very haphazard and is usually just splashed on the bottom and not up the sides and is really not thick enough.
