Early German AFVs

Here's an 88 from Flames of War:

A Ferdinand, also from Zvezda:

A Panther from Flames of War:

A Panzer IV F2 from Plastic Soldier Company (I should have just built all of them at once):

A 3D-printed Tiger from Plastic Anvil Workshop on Etsy.  Nice for the price, but I think I prefer the FoW version better:

Very nice indeed! Do you do a pin wash or, what do you use for this? I like the dark recessed lines.

I like your method. I use Black Temper paint mixed with water and 1 drop of dish soap (breaks the elasticity of the water). I use a small glass baby food jar and mix 1 part Temper paint to 3 parts water and the drop of dish soap. I use a large soft brush and gently mix it up. First I give the model a coat of Dul-coat. After that has dried I do a complete coverage doing one side at a time ( right, bottom, left and top last letting each side dry before going on to the next). Once this has dried I use plain water and a paper towel (to soak up excess from brush) I get the brush wet, dab some of the excess water off on the paper towel and remove the wash from the raised surface leaving wash in all the recesses. You will have to rinse the brush often and continue. What I like about how I do this is if I don't like the outcome I can remove the wash and do it over with no repainting. It helps to go from the top down when removing the wash. On desert paint jobs I do the same but with Brown Temper paint. Once your satisfied with the results give it another coat of Dul-cote to seal it. Next is to do the dry brushing of the raised surfaces. This method has worked for me for years.
