I used Bondo to make a little more texture then base of black primer then Chrome. Applied mustard over chrome then dark grey spray. More mustard and dull yellow spray. Again more mustard and then spruce green spray. Then I used some aluminum model paint on brush to dull the chrome in spots. Finally I used a mixture of charcole green and black on brush to apply burn marks and then washed them dull with air brush thinner on a clean brush and blotted dry with sponge. The flash on my camera really keeps the lighter shades from showing, in normal lighting the burn marks are actually pretty light and you have to be close to see the details. 8)
