The railings that are carrying the flak has received their rust finally.

First of all couple of coats of hairspray, then a wide variety of rust related tamiya acrylic colors thinned with WATER, paint was tedious because when thinning with water the paint must be extremely light and after each pass the should be dried somehow, either air via double action airbrush or hairdryer. After the colors are visible enough time for oil wash and pigments. Finally cocktail stick to the rescue to scratch the rust from logical places like edges or whereever the crew would walk.
