A coated substrate comprises a strippable intermediate coating atop the substrate and a strip agent-permeable waterborne overcoat adhered to the intermediate coating, wherein the dried overcoat is less trippable and more wear-resistant than the dried intermediate coating. When the overcoat eventually becomes worn and must be renewed, a strip agent (e.g., chemical strip agent) can be applied to the overcoat. The strip agent penetrates the overcoat and attacks the intermediate coating, thereby enabling removal of t he intermediate coating and overcoat without aggressive removal techniques such as sanding. |
