This here brush…I tell you. I used it for like the last three years to coat all my work in high gloss medium. It was one of those crappy brushes from a six dollar set of brushes. I used it to mix paint too. This brush was a beater. It lived a life much greater than it’s intended purpose. It’s bristles were all fused with medium, like a glossy wad of prickly hair. I used to get bored and peel the medium off of the individual bristles. I threw it away…I hate throwing stuff away. Maybe a homeless guy will dig it out of my dumpster and paint something sweet.
