An asphalt coated roofing shingle including a mat substrate saturated with asphalt, a top asphalt layer on a top surface of the mat, a bottom asphalt layer on a bottom surface of the mat, a granular layer on the top asphalt layer and a layer of melt-blown fibers applied to the bottom asphalt layer. A method for making a lightweight roofing shingle including the steps of saturating a mat substrate wherein the mat substrate has a top surface and a bottom surface; applying a top asphalt layer to the top surface; applying a bottom asphalt layer to the bottom surface; applying a layer of granular material to the top asphalt layer opposite the mat after the top asphalt layer is applied to the top surface; and applying a layer of melt-blown fibers directly to the bottom asphalt layer after the bottom asphalt layer is applied to the mat substrate.

A method to prevent corrosion of a susceptible article of a two-article system, in which first and second articles of the two-article system have surfaces facing one another and in which the two articles have different anodic indices includes applying a coating material to the surface of the first article and curing the coating material on the surface of the first article. The method further includes contacting and securing the surface of the first article with the surface of the second article. The two articles exhibit substantially no corrosion following exposure to a corrosive environment under standard GMW17026 for a 15 year simulated test.

A longitudinally adjustable flow divider situated in the particulate material path of a spinner spreader between the bin and the rotatable disc divides the particulate material so that the particulate material is dischargeable on to the upper surface of the rotatable disc on first and second laterally spaced apart longitudinally oriented drop lines. An actuator operably connected to the flow divider adjusts a longitudinal position of the flow divider to longitudinally adjust drop points on the drop lines at which the particulate material is dischargeable on to the rotatable disc. Longitudinal adjustment of the drop points along laterally spaced apart drop lines on one spinner disc permits control over spread pattern to help achieve uniform distribution of the particulate material on a ground surface.
