Don’t listen to all that newfangled steel wool and scotch nonsense. Use the
sharp volcano dust..
No, really, Any of the methods to knock back the high gloss of shellac will
work. Personally, I avoid steel wool, because a lot of what i do is oak, and
tiny steel dust particles do not mix with oak. (Sometime later they reveal
themselves as rust spots) I use scotch brite, but it steadily goes blunt (as
does steel wool)
Hence - volcano dust.
with thanks to Paddy for making me consider why I ‘always’ do the same thing.
