A surface marker resin formulation is provided that includes a linear aromatic polyester or a co-polymer thereof. The resin is dissolved or dispersed in a solvent exclusive of naphtha. An inorganic particulate having an average maximal linear extent of between 10 and 130 microns present from 22 to 41 total weight percent. A process of marking a surface includes two articles being brought into a pre-selected alignment to define a surface. A continuous bead is applied to the surface. The solvent evaporates to a state of dry-to-touch in a time of between less than 60 seconds to mark the surface. The formulation is readily applied from a pen to achieve a controlled bead width. The drying of the formulation by solvent evaporation yields full hardness in 24 hours under standard temperature and pressure as measured at 0% humidity.

The present invention provides a water-based coating and/or coating system that can be used to form sag resistant wet layers or coatings on a wide range of substrates. The coating system is particularly effective for protecting metal-containing substrates, such as intermodal cargo containers, against corrosion. As an overview, the present invention provides water-based compositions suitable to form primer coats on substrates. Desirably, the primer incorporates a high level of one or more CAS agents for excellent sag resistance while drying in a broad range of relative humidity environments. Alternatively, modifications can be made to control temperature and humidity during spray application and drying as a way to increase sag resistance of the coating.
