The invention relates to the technical field of automobiles and discloses an automobile protection rod formed by polyethylene blowing and a surface coating method thereof. The automobile protection rod comprises an integrated rod body formed by hollow polyethylene blowing. The rod body is coated with a decoration layer. The surface coating method of the automobile protection rod comprises the steps of (1) surface treatment; (2) priming paint spraying; (3) finishing paint spraying. In the surface treatment step, a flame gun is adopted for carrying out activating treatment on the surface of the rod body, the temperature of a flame treating head of the flame gun is 1000 DEG C, and the moving speed of the flame treating head is 0.1 m/s. By adopting hollow polyethylene blowing formation, the mobility is good, formation is easy, the cost is low, the weight is lighter, the shock resistance and buffer performance is good, the structure is integrated, the number of parts on the rod body is effectively reduced, and the assembly process of the automobile protection rod is simplified. In addition, the rod body undergoes surface treatment in advance, so that the problem that the surface coating performance of polyethylene material is poor is solved, and the automobile protection rod is customizable in appearance and good in surface weather resistance.
