Mark-It Blue Spray Solution Colorant

Mark-It Blue is used as a spray solution colorant so it can be easily recognized where spray has been used. Avoid overlap sprays, missed spots, and indications of drift under windy conditions. The blue color breaks down in head and sunlight (the more of each, the faster the breakdown). Will not permanently stain foliage or skin (but if spilled on fabric, wash off immediately before it dries).
