<p>A method for protecting a coated surface of a vehicle, in which a homogenous cured protective film can be obtained in a short time and no special protective-film aging step is necessary after completion of the treatment of all surfaces. The protection method comprises forming a cured protective film on a coated surface of a vehicle using a moisture-curable silicone-based protective agent which contains an alkoxysilicone oligomer as an essential component and has a hydrolysis rate regulated by means of a hydrolysis catalyst. The silicone-based protective agent is a protective agent obtained by diluting an alkoxysilicone oligomer having a specific dynamic viscosity with a mixed diluent solvent that comprises a water-miscible solvent and a sparingly water-soluble polar solvent added thereto. A cured protective film is formed through a section coating step in which this silicone-based protective agent is applied to the coated surface of a vehicle while spreading the protecting agent by means of supplied water.</p> |
