=====Sand Paper=====

Most people use sandpaper. While sandpaper usually works just fine, it usually comes warped/curled, so you run the risk of making your bushing uneven because the side of the bushing which is closer tho the warped part of the sandpaper, will automatically have more pressure applied to it, making your bushing uneven. So if you want to use sandpaper, make sure to properly straighten it out before you start lapping your bushings. This can be done by bending the sandpaper in the other direction and/or by taping it down to a straight and sturdy surface. You will also need a hard, flat surface underneath the sandpaper, like a slab of marble. A wooden desk or countertop is not hard enough.
