Hello All, I am wondering if others are having issues with the durability of brushes and shape loss? Especially after using products like Advance? I grew up using Purdy Nylox, and have tried most Purdy lines as well as a couple of offerings from Wooster and Corona. I know quality and craftsmanship has gone down, but I'm hoping I'm missing something. It just seems like when I wasa a kid (15 years ago) I would have the same brush forever. Now, even after I wash out brushes with soap and water and use my brush comb and hang to dry, they still end up flaring out and splitting. Should I be exclusively using paint thinners? I do sidewalk pat, but not hard... This happens to brand new brushes. The only ones that seem to hold up are Chinex brushes...is that my answer? I don't mind padding money to bids for brushes, but I would prefer to take care of my equipment properly. Thanks!
