Another update, I'm rolling right along with these Shermans. I want to finish the first three which have been painted, (Base Coat), for a long time and can take the Rectified Turpentine wash with no concern about losing paint.
I began with the M4A1 76mm. I used my old school raw umber artist's oil and rectified turpentine wash. If this is done correctly, and washes are notoriously applied incorrectly, it will do much of the weathering for you. As you remove the wash by blotting, not rubbing, if you pay attention, you can remove it in places you want it removed and can save you a lot of work dry brushing later!
This is the M4Ai 76mm, completely washed and blotted, next to a base coat only M4A3E8. It dried overnight to a nice totally flat finish. I broke off several pieces including the left side turret add on armor. That always happens and will be reattached later.
Then I switched the two for a closer look.

Then, here are both with wash completed.
Next, all three washed and after drying, ready to begin further weathering!
Another angle.
I'll let them dry for 24 hours while I prepare the tracks, (Building, painting and rusting), and maybe start preparing all the figures that will be on them.
To be continued!
