Enamel type streaking for modelling.
Light grey colour is ideal for creating dirt streaks on light or white colored surfaces. Also suitable for other effects, such as adding chromatic richness to any piece or surface. Shake well before use. Apply your streak with a fine pointed brush in irregular vertical lines from the upper parts of the sides and let the paint dry for about 10 minutes. Next, take a flat brush moistened in White Spirit and swipe with little pressure over the earlier applied streak to soften the effect and create a natural look.
