The present disclosure is directed to a method for reactivating a co-cured film layer disposed on a composite structure, the method comprising applying a reactivation treatment composition comprising at least two solvents and a surface exchange agent comprising a metal alkoxide or chelate thereof to the co-cured film layer, and allowing the reactivation treatment composition to create a reactivated co-cured film layer, wherein the co-cured film layer was previously cured at a curing temperature greater than about 50° C. A reactivated co-cured film layer and an aircraft part having a reactivated co-cured film layer are also provided.
