I have a Simpson Chubby #3 in Super Badger and it's a 2 band. I bought it before Simpson was sold. I just read an article that said some 3 band brushes are bleached to look like 2 bands. Is that true? Are there 2 band brushes that are natural and not bleached? I have been told that 2 band brushes work better with soaps so is that also true?
