The 4-wheeled applicator is a really easy to use line marking machine. With a lightweight and compact design, the two wheeled line marker paint applicator can be used comfortably over longer periods to mark lines and all kinds of marks, shapes and patterns. Anyone can use this aerosol line marking machine without needing any experience. While the rubberized wheels allow for superior grip on a variety of surfaces, the guide disc that sits on the inside of the wheel hub is designed to give better quality and sharper line edges. Due to the nature of aerosol spray paints, a degree of pixelation or overspray is to be expected, so it is recommended to mask off using tape if especially crisp line edges are required.
