Items needed:
Gloss/satin varnish
Oil paint
Thinners. ( i use an Artists thinners which has less odour)
Something for the oil paint to go into and a separate one to clean the brushes, ( I use little pie dishes)
Brushes.
Paper towel.
First off paint on all your base colours then Varnish the model, i'd recommend two coats
Satin and gloss varnish both have a different effect and it depends on the look and effect your after.
Gloss allows the paint to run using capillary action and gives a much finer line and cleans better.
Satin allows some to leach into the surrounding area.
I have used Satin Varnish on these.
Put some thinners into a dish and then add Oil paint to it. The thickness of the mix depends on what you want to achieve but it should be very dilute, almost like squash.
then its simply a case of loading your brush with the mixture and touching it to the crease you want the wash to urn into, if it doesn't run chances are the mix is too thick, if it runs but you can't see the paint its too thin.
any over spill can be cleaned up with a spare brush dampened in thinners, no rush for this as oils are slow drying you have several hours.
for the shadows I use a thicker mix ( milk like) and deliberately over spill, then with a damp brush I pull the mixture down towards where I want the shadow to fall. this blends the line and also blends in my previous airbrush blending.
I used Black for the pin wash and blue for the shading.
On Cream models like Deathwing I use Burnt Umber for pin washes.
Hope this makes sense and you can see what I was trying to achieve in the pics
below. Next step is using the original light green to add battle damage and then use weathering powders to age it.
Thanks for looking and please leave comments.
