Speedpaint over Dirty Down Rust Base Coat

Experimenting with Dirty Down Rust as a base coat under The Army Painter Speedpaint 1.0 and comparing brush Vs airbrush paint application to see the variation in appearance and bleed through for weathering in a Grimdark style.
Using a masking compound or texture paint prior to Speedpaint application creates more interest in the finish.
Dirty Down Rust can be mixed with Speedpaint medium to create a self concentrating rust effect.

Nice experiment! I always wondered how it would act under a layer of paint. Thanks for posting this!
