PROBLEM TO BE SOLVED: To inexpensively remake a guardrail by removing rust and dirt therefrom by powerful blasting and by performing thermal spraying and painting while preventing dust from spattering during the operations. SOLUTION: This guardrail remake system comprises a blasting vehicle and a thermal spraying vehicle. The blasting vehicle runs along the guardrail, and removes the rust, dirt, and paint adhered to the guardrail by projecting a blasting material from a blasting device mounted on the vehicle toward the guardrail. The thermal spraying vehicle runs along the guardrail following the blasting vehicle, and forms the thermal spray coating on the guardrail by projecting a thermal spray material from a thermal spray device mounted on the vehicle toward the guardrail.
