Any thoughts on this "Ratio" Oil Depot Kit I just finished? Im thinking that I may have overdone the oil stains on the pipework? I tried quite a few methods of painting the tanks black but still have them look like they are made of steel and not just painted plastic. Nothing seemed to work until I found an article on the web about how to do it. It was very easy in the end and Im quite pleased with the result. I painted the tanks Polly Scale Engine Black then I lightly drybrushed Polly Scale Flat Aluminium in different spots. It makes it look like the black paint is worn away in parts and the steel is showing from underneath. Thanks, Troy.
