[font=trebuchet ms]I would spend a couple bucks on a proper ScothBrite abrasive pad without the sponge. The reddish-purple ones should be about right. One of them is plenty. Start out very lightly until the abrasive gets worn away enough to allow more pressure. The plan is to just break up the surface finish a bit, not to remove the paint. Wipe the neck frequently with a clean cloth to remove the dust before it has a chance to get into places where you don't want it, like the strings or your pickups.[/font]
