Enamel type streaking for modelling. Create realistic dirt streaks and grime effects easily with this dirty color. This enamel product creates realistic streaking grime effects on your models. Easy to apply. Very realistic coloristic color. Shake well before use. Apply your streak with a fine pointed brush in irregular vertical lines from the upper parts on the sides and let the paint dry for about 10 minutes. Next, take a flat brush moisted in White Spirit and swipe with little pressure over the earlier applied streak to soften the effect and create a natural look. Easily imitate the streaking dirt, for example, in a Dark Yellow or Grey paint, using this color. Use a fine brush to draw the lines and a thick flat brush dampened with White Spirit to stump the lines.
