Federico Collada advised in his recent edition of Blitzscales that he will no longer be publishing future releases since his other business endeavor is occupying most of his time.
His techniques have taken me to the next level while using primarily acrylic products. His Armor weathering techniques are amazingly effective and very easy to master, and application of such exceeds the results I was getting with typical methods using enamels and oils.
Another excellent Spanish modeler, muchas gracias por todo Federico.
