Disclosed are environmentally friendly, substantially all solids coating compositions which are curable using ultraviolet and visible radiation. In certain embodiments, the disclosed coating compositions are suitable for coating flexible objects and/or objects having angular features, such as, but not limited to, flexible metal objects with angular features. In other embodiments, the cured coatings have improved slip properties and at least 6 H hardness. Such embodiments can served as substitutes for "hard chrome" coatings, TEFLON.RTM. coatings, coatings comprising TEFLON.RTM., or TEFLON.RTM. like coatings. In addition, methods are disclosed for coating surfaces, or at least a portion of the surfaces, and curing of the coated surface to obtain partially or fully cured coated surfaces. Furthermore, articles of manufacture incorporating fully cured coated surfaces are disclosed, including, for example leaf springs, hydraulic rods and cylinders. Also disclosed are methods, processes, production lines, articles of manufacture, and factories which incorporate these environmentally friendly, substantially all solids coating compositions curable using ultraviolet and visible radiation.
