I've tried flexhones and own more of them in .687 than what brush research sells.
I never saw a quantifiable difference... And can come up with no theory for why a flex hone would be better than other finishing processes.
Do you have a theory, Smith, for why this is a superior method? You should remember that you're well respected and held in the highest esteem on MCB.
One strong disagreement doesn't mean we're all snakes.
