The present invention provides a method for protecting intermodal cargo containers against corrosion that comprises applying on the container a water-based composition suitable to form a base-coat on the substrate and, optionally, an aqueous top-coat. Desirably, the base-coat incorporates a high level of one or more CAS agents for excellent sag resistance while drying in a broad range of relative humidity environments.
