Hedgehog Armoury full polish starts after planishing is finished.
40 grit belts are used all over the piece. At this point, areas that need more planishing can be attended to, and the 40 belt repeated.
After this, I work through the belts in order 40, 80, 120, 160 grit.
Then come the wheels. These wheels are 40, 80, 220 and 400 grit.
Why the overlap? The 40 grit wheel must undo some of the work of the 160 grit? Yes it does, but wheels can get into areas unreachable by the belts, so we go a little backwards in the hard to reach areas in order to go forward.
Mild steel then receives the grey compound, then the white compound, then the bare fluff wheel.
Since 2016 have also used a product called “Liquid metal polish” with a mop afterwards for a final pass.
