Bitumen from Abteilung 502, 20 ml in a practical tube.
Oil paints specially formulated for modellers reducing the typical amount of linseed oil so stains and marks will not be a problem anymore. Forget about those cardboard pieces used to deoil the paint and obtain incredible subtle effects using this amazing range. We recommend to apply them on surfaces previously varnished in satin. This is a slow dry paint, so you will be able to correct and modify effects as it dries.
