In non-automotive applications, it is used on ATV fenders, kayaks, canoes, dirt bike fenders and gas tanks, motor home water tanks, and agricultural water/fertilizer tanks. Because Polyethylene is very waxy, it is almost impossible to get quality repairs using adhesives. Welding is the best repair method for polyethylene. Polyethylene is naturally a translucent white color. No pigment has been added to make less visible repairs when welding natural polyethylene parts. This package contains 30 ft. (9.1 m) of black welding rod. Each rod is 12 inches (30 cm) long and is 3/16th inch (4.7 mm) diameter.
