Just finished this tonight. Tamiya's 10hp Tilly in RAF markings.
The blue is Tamiya Medium Blue, the tires and interior are Testors Interior Black, the canvas cover is Humbrol 110 (Natural Wood). I thinned the Tamiya and Testor's with DTL 876 in my standard 50/50 mixture (gotta love consistancy!) and hand brushed the canvas. Details were picked out with Floquil Bright Silver and a "0" brush.
The body was washed with Citadel Badab Black to bring out definition in the grille and wheels, and I used a AK Interactive Streaking Grime wash on the canvas. I then used Testor's Ultra Gloss Clearcoat straight from the rattle can, and decaled on top of that. A final coat of Testors Dull Coat thinned 50/50 with DTL 876 was then airbrushed on.
The final step was to take the windshield and hand paint the trim/wipers with Interior Black and snap it into place.
Cool little truck!
