The versatility of oil-based paint markers have made them an ideal solution for many industrial applications that require a specialized paint marker to withstand harsh environmental conditions. Ideal for use on a variety of surfaces including metal, wood, iron, plastic, glass, rubber and cloth, these markers tote excellent durability and wear resistance from common solvents and extreme temperatures. Although some paint markers come with an already primed paint tip, most solvent-based paint markers do not.  To use these markers, first shake and mix thoroughly before removing the paint cap. Next, push down gently on the spring loaded tip and pump it once.  This process will help move the paint from the barrel of the marker to the non-charged empty tip. However, you may notice that no paint appears at first. Be patient and do not over-pump. Repeat one or two additional times, until you see the paint begin to materialize. Once your work is complete, be sure to put the cap back on tightly. When not in use, paint will harden when exposed to air.  This hardened tip can obstruct the flow of additional paint through the marker making it unusable. Look for caps with vapor seals which will are designed to keep the air out and help extend the life of your marker.

Although the uses and applications of oil-based paint markers extend well beyond the industrial realm, users must be mindful of the fact that many oil-based markers contain toxic chemical solvents and should not be used by unsupervised children. Fortunately, manufacturers such as Markal, now offer xylene free paint products that help reduce user health risks and  and eliminate California Proposition 65, EPA HAPS and SARA 313 concerns in the U.S.A..
