Yes Mateo, with the Richeson 9010 brush, you save a lot of solution, but as I said, you can over do it and get too thin a coat.
The Arentz book gives these amounts for Hake brushes, they absorb way too much solution. I dont know if he will inlcude the "magic brush" in his new edition.
Trust me on this one, if you can get one! Clay turned me onto this brush and it is one of the best things he could have done for me.
