With this product we can create a streaking grime effect on the light tones of the interior of all of our vehicles. Shake well before use. Apply your streak with a fine pointed brush in irregular vertical lines from upper parts on 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. Enamel type streaking for modelling.
