Busses, Trucks, and RVs are different than regular automotive since they are built on long sturdy I-beams designed to bow and sway with the weight. Along with all the automotive surfaces like painted metals, plastics, cloth, rubber, and glass, we also supply markers perfect for writing on rough steel I-beams used in truck, bus, and RV manufacturing. We recommend the Mighty Marker® Metal Rolling Ball Point Marker MM-66 and MM-99 for such rough steel surfaces.
RV manufacturing requires touch up pens to heal scratches made to all the different surfaces during the manufacturing process. Arro-mark® manufactures and supplies pens for this purpose as well.
