Nice post on the process you used for the Misono and the Nick Wheeler thread. Nick is insane.
I had no idea that using some type of acid etch was so common. It makes me wonder if there's a way to do it without the etch; I sure didn't have much success until I started using an etchant.
Next time I have time that needs killed, drinks that need drank, elbow grease to burn, and a honyaki that needs messed around with, I might have to pick up some of that WA powder.
So far though it's both reassuring (that I wasn't wasting my time / struggling with something that was easy for other people) and a little disappointing that there is no "easy" way to create this finish. Maybe using a power buffer to get the the initial sand-paper scratches out?
