Spiral Stitched wheels are for initial cleaning to remove old finishes and rust, while Loose Muslin wheels are for smoothing between grit changes and final preparation before bluing.
It's essential to use multiple sections to match your motor's width, with a minimum of three per wheel, and dedicate wheels to specific grit numbers for efficiency and better results.
Mark used wheels with the grit number and rotation direction to extend their life and improve the polishing finish.
