One of the largest sellers for heavy duty applications, the Pumper contains over 11 cc's of an industrial paint formula that bonds to metal, most plastics, wood, solar panel fasteners, wood, masonry and millions of other surfaces. Manufactured in Canada and imported by us for the industrial market. Excellent for heavy duty applications requiring long UV resistance, marking on oily and dirty surfaces and surfaces that wear the nibs out (because you get two with each marker!).
