Just saw this.
Branson Charcoal 03156 654771 Mfgr. for Branson by Raabe Co., out of Wisconsin. 800 966 7580. I bought mine from my dealer....about $16 a can. On the red, I matched with Rustoleum Cherry at wally world for about $ 3.50. Real close match. Don't know how it would stand up to sunlight like OEM paints will.
Haven't found a source for Charcoal that's convenient....really haven't tried that hard.
