Getting ready to use it for the first time. Can you change the shade by using gloss, semi gloss or flat blacks under polished aluminum. I also have the airframe aluminum. I am building the Chalanger 1 with the 4 engines and would like to break up the colors of all the aluminum. I also have the magnesium. This kit is one of my holy grails! Also getting the blue from MCW hope it will be as nice as it is in my mind!
