Yeah Steve.... I even still have some of my Dad's brushes. One of which was HIS Dad's. My grandfather was a professional painter and passed on his passion for taking care of your tools to my Dad.... who passed it on to me. I still have every single brush cover (you know, the cardboard bristle cover with the tie string thingie that you wrap around and around that little button) that originally came with my brushes. Every one of my brushes look like they could go back on the wall at Sherwin Williams or Porter.I Agrey with JW if you use the same base as the product you are using it will not hurt the brushes I also have some old ones that I would hurt anyone trying to take them. I use a brush comb and a fine wier brush, rap them in brown paper and store them bristles down but not touching the bristles.
