Please post your data for REX powders in this thread. Here is some information about these powders gleaned from the internet: Rex 0 = Rex Blue = Rex Azzurra = Rex 24 (similar to Bullseye and WW 231) Rex 1 = Rex Red = Rex Rossa = Rex 28 (similar to Red Dot and Clays) Rex 2 = Rex Yellow = Rex Gialla = Rex 32 (similar to Green Dot and International) Rex 3 = Rex Green = Rex Verde = Rex 36 (similar to Universal) In America, these powders are available from Graf and Sons and Powder Valley.
