This model is a Stu.Pa.IV, Brummb‰r (early, from cyber hobby).
After applying AK088 Worn Effects to paint the proper rust shade we have used subtle layers of brown and red. AK708 Dark Rust and AK789 Burnt Umber.
Once blended the rust color with the vehicle color, without covering completely the previous layer, the result is very realistic and convincing.
The welding lines have been painted with Mister Color Chrome Silver.
The wheels have been painted and weathered separately.
The color AK015 Dust Effects is perfect over the red color to enhance the effects of accumulated dust and highlight the volumes.
The white metal tracks are painted with AK015 Dust Effects after having them primed and weathered, paying special attention to the polished metal.
After painting the factory marks we have applied several oil and grease shades to achieve a more realistic result. It is important no to overdo the effect or it will look fake.
