I completed the toy as per the box instructions but closed the rear doors and left out all the gubbins that went within. You may have noticed the cab is glazed. I did this by cutting thick card to fit and glue in place. Painted a dark blue with a lighter blue worked into the wet paint to produce the highlights. The vehicle was painted Vallejo 'Sand Yellow' and then a wash with that Army Painter stuff. Once dry highlights were applied using the Tamiya weathering powders and the cheeky little make-up brush they provide. Based on foamcore and terrain is the usual mix of PVA and a sand colour with sand and gravel sprinkled onto the wet mixture.
Sadly I do not possess a sand-table. It's too wet to photograph outside so a piece of sand-paper is standing in for The Western Desert.
