Thanks Jim, I used a black base coat to start. Very light grey over that and washes, pastels and airbrush to weather it. I taped off certain panels and used a soft paint brush and pastels to darken up some panels. And last but not least I used white, grey silver and some dark grey paint on a tiny brush to create chips in the paint. I tried to recreate a "blotchy" chipped look. Also ran some fine sandpaper over some of the raised areas to bring out some black base coat. The droid is made with two tiny balls of epoxy sculpt.
thanks
