I repair furniture for a living and these brushes are the cheapest and most convenient solution for pre-sanding before painting. I've been looking for a wheel like this for a long time and it's just hard to find something suitable for this application. The downside is that the bristles are still a bit stiff to allow the wheel to fall into deep spots, but the positive thing about these wheels is that the wheel is segmented and you can add or remove these as needed, which somewhat solves that Problem of stiffness when bending. I use 120 grit, I might try a size finer later, but if the bristles could be more flexible that would be better than what you can get. The 1/4 inch shank is long enough to get you in the right places.
