The following steps cover how to do the DA emblem on the shoulder pad. Unfortunately it doesn't photograph very well. This way of doing white will work for just about any place that you want white on a mini as well.
Step 14. A base coat of Quaker Gray from Delta Ceramcoat is put down. GW Fortress gray will work as well.
Step 15. Over this a coat of GW Ghost Gray is put down.
Step 16. Covering about 3/4 of the GG, I put down a coat of 2 parts Ghost Gray/1 part Skull White.
Step 17. Again, covering about ¾ of the previous color, I use a mix of 50-50 Ghost Gray/Skull White.
Step 18. As with above I give it a final coat of 2 parts Skull White/1 part Ghost Gray.
Step 19. Capping it off with a thin highlight o Skull white.
