What's wrong with my brush?
Purdy is a good name brand. Yet my Purdy nylon/polyester brush is having a "bad hair day" that is getting worse the more I use the brush.
The hairs are curling back from the body of the brush, as opposed to lying straight. It's starting to look like a pom-pom. When I clipped the bad ones so I could continue work, more started curling back to take their place.
I'm using the brush with shellac, and it was new for this job. I never soak it in solvent. To clean, I wipe off what I can, apply a few ml of clean alcohol to the brush, work it in with my fingers, and wipe it out again with a paper towel. Repeat that once or twice more. Then comb with a brush comb and mold it to a chisel shape to dry.
