what is the best type of brush for epoxy and /or varnish? something reusable? how do you clean it out? i have been using throw away " chip " brushes so far, and bristles keep coming off, and they just suck in general. i went to an art supply store today and bought some cheap artist brushes. will anything clean epoxy out of a brush? acetone maybe? i will try since this is getting expensive.( i used three today alone)
