I didn’t want to use the STAP so I reposed the figure and bolted it to the wooden base. I drybrushed the heavy-wear areas with flat aluminum paint, and added a dark wash and some pastel powder here and there.
Starship Modeler (www.starshipmodeler.com) offers a cast-resin blaster rifle that’s in scale with the figure if you’d rather model yours as a ground trooper.
I had to play with the color quite a bit on mine. The droid was painted a base color mix of sand and white. I used several earth tone pastels and colored pencils for the weathering. The stap was painted to match the box photo by mixing yellow zinc chromate and red until I got that rusty orange color.
The best suggestion is to skip the instructions and paint it the way it looks right to you. There are a few good reference pics on line but the stap and droid combo seems a little limited. Just remember to get us some pics of yours when your done, we live for pics [dinner]
I used Testor British Gulf Armor Light Stone (No. 2136) for the droid’s base color. I had to go back and double check; I used a silver art pencil for a lot of the wear and tear, and I used a soft lead pencil to outline a lot of the panel lines.
I hate to mention it, but there’s a whole chapter on building this model in my book, A Galaxy Far Away: Building Star Wars Models. You might find it helpful. The book’s just gone out of print, by the way.
