Claim 0:
1. A method to prepare an aircraft surface, comprising:
depositing a first solution on a substrate on the aircraft surface, the substrate having a first charge, the first solution having a second charge opposite the first charge;
removing a first amount of the first solution deposited on the substrate using a washing fluid to form a first layer on the substrate;
collecting a recovered solution including the first amount of the first solution and the washing fluid;
reconstituting the recovered solution to provide a third solution;
depositing a second solution on the first layer, the second solution having the first charge; and
removing a second amount of the second solution deposited on the first layer using the washing fluid to form a second layer on the first layer to prepare the aircraft surface.
