A method is provided for washing, drying, applying a curable coating, and effecting the cure of such coating on a variety of substrates, such as metal, for example steel, plastic and wood. A particularly effective drying procedure based on the generation of a dehumidified and filtered air stream directed substantially parallel to the wet substrate allows for a significant decrease in drying time while maintaining coating effectiveness.

[What is claimed is:] [1.]washing the substrate;placing the substrate in a drying booth in a batchwise or continuous manner;drying the substrate by continuously generating and circulating within the drying booth, a dehumidified and filtered air stream, wherein the air stream is directed in a substantially parallel manner at a rate of at least 50 ft per minute across the substrate surface in the drying booth and has an RH value of at least about 9% at a temperature up to 105.degree. F.; andproviding at least one humidity sensing device within the drying booth to monitor an RH value of the air stream and disable the circulation of the air stream within the drying booth when the RH value of the air stream reaches a predetermined value.
