Does the job for a spindle chair. I resorted to a large round water color /acrylic brush to do groove valleys and tight spots. This brush will shed occasional bristle filaments so be ready to brush/tweezer these away while paint wet and touch up with art brush as well as needed.
Covers well .Watch out for tiny droplets and paint berms as these will dry to an alligator skin finish if not quickly brushed out . These can be hard to see on edges and irregular surfaces until they dry and form.
The flexible property is very useful. All tend to have a relatively fine grit...even the "medium". A grittier version would be better for initial sanding of glossy factory paint to get some deeper tooth going.
