PAINT BLACK 18oz. This product is a black water-based permanent marking ink from the Seymour brand. Ideal for banners because of its quick drying. It is applied in an inverted position to produce clear lines. It is durable, safe on grass and cannot be removed by water. In addition, its anti-clog mark is unwashed and meets APWA color standards. One of its advantages is that it dries in just one hour and can be applied manually or with a Z-605 marking gun or Z-606 marking stick.
