Enamel Product.
With this enamel product the modeler may easily represent streaking effects left by salt on vertical surfaces or horizontal areas of any ship. 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.
