The method

Section by section.

Each heading links back to the moment in the source video where it begins.

One video is one workshop's account, not a complete method. 3 of 3 steps here are not fully settled by this source — it leaves out what a correct result looks like, or how the step fails. Those are marked in place below.

Polish with kikumo

Apply kikumo to a cloth and polish the coated surface in circular motions with firm pressure. Continue until dullness and abrasion marks are removed. Once the gloss emerges and abrasion marks disappear, stop polishing with kikumo.

When it is rightGloss is pronounced and abrasion marks are gone.
