My goal of getting the Brummbar complete this weekend wasn't quite realized as I often underestimate just how much time some steps will take when this close to the finish line...but better to get it done right than rush things too quickly!
Picking up from the last update, the weathering continued with the application of a pin wash using thinned enamel MM Burnt Umber and a pointed detail brush.
Because of the flat finish surface that the dot filters created, the pin wash has a tendency to "bloom", so that meant coming back with the same detail brush and some clean thinner to tighten things up.
With that step done, the entire vehicle received a sealing coat of MM Lusterless Flat in the spray can. I let that set for about an hour in the spray booth with the vent fans running to dry thoroughly before moving on to the pigment weathering.
The pigment weathering for the lower hull began with a wet application of Mig Dark Mud pigments. I use regular tap water with a drop of liquid Dawn dish washing soap added to break the surface tension and apply the mix with a medium round brush.
After the met mix has air dried, I use a stiff bristled brush (while wearing a dust mask to avoid inhaling the particles) to remove any loose/excess pigment. More pigment is removed and adjusted using wet q-tips until I get the look I want.
This process was applied to the lower hull and running gear on both sides as well as the hull front and rear. Next up will be giving the tracks their treatment and getting them ready for installation.
