USING SANDING BACKING PADS (FIG. 14}
Choose the proper grit sandpaper for your application. Sandpaper
is available in various grits. Coarse grits yield faster material removal
rates and a rougher finish. Finer grits yield slower material removal
and a smoother finish.
Begin with coarse grit discs for fast, rough material removal. Move
to a medium grit paper and finish with a fine grit disc for optimal
finish.
