Ok, here's the step by step finishing the turret.
First Vallejos polyurethane primer was applied.
Black airbushed on the edges and on details. Other lines to diffrentiate surfaces aswell.
Base gray color. Started airbrushing where there was no black color, after that fading the seams together.
Base gray lightened. Stick to the centers and create highlights.
3rd coat even more lighter. This time I used masking tape to modulate different surfaces to have hard edges.
Sandbags brush painted with Vallejos dark sand.
Brown wash. I used AK's brown wash for wood decks. You can use oils or enamels don't really matter if you use acrylics as base.
For me using products that are already ready to apply from a jar works better as it's so much easier when you have A LOT of different steps.
Cleaned excess with white spirit. Wiped excess off the brush to keep the cleaning under control. That way you can control the effect.
My motto is less is enough as too stark washes and drybrushing tends to look too artificial and bad.
Blastbags painted with H321 light brown. 2nd coat lightened with white about 50%.
Same brown wash applied.
First 2 cleaned for comparison.
Black wash with AK's wash for nato tanks. Again keeping it clean and not overflowing the wash.
And cleaned with white spirit.
Next some streaking with AK's white for salt stains. I brushed streaks all over the turret.
Blended them with white spirit. Damp the brush with white spirit then get the excess off with a paper towel then start streaking and blending the paint in the same direction as you painted them.
Once again I kept it subtle.
Same with dirt color. I used AK's streaking grime.
And cleaned.
I applied Vallejos satin clear. Just a couple of light coats.
After that I drybrushed. Light sand color for the sandbags and blastbags, light gray for the turret.
I focused on brining details up. (ladders railings etc.)
Last but not least I applied pigments. I sprinkled them with a brush. I used Migs track brown and rubbel dust.
Fixed with white spirit. To top it off I used AK's engine oil for the fluid marks.
Now to add the 2 triple 25mm and it's done!
