Ageing of a military vehicle is probably one of the most interesting phases of the hobby.
Once dry the color I have begun the process of aging of the medium with the aid of the now known all over the world, the filter method (95% thinner-5% tint) that allows give a greater richness of color, in this case I used Humbrol enamel colors yellow, blue, pink and sand in several subsequent steps and waiting patiently for the complete drying of each filter.
