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 the , intermediate coating and overcoat without aggressive removal techniques such as sanding.
