A method of treating a contoured surface with surface treatment layer includes applying a surface preparation layer along the contoured surface and applying a basecoat layer on top of the surface preparation layer. The method further includes stabilizing the basecoat layer to prepare a basecoat surface along the basecoat layer for one or more subsequent layers of the surface treatment coating and jetting a decorative livery layer along the contoured surface using one or more ink jet print heads. The method further includes applying an adhesion promoter on top of the decorative livery layer and stabilizing the adhesion promoter layer to produce a desired bonding surface along the adhesion promoter layer. Additionally, the method includes applying a clear coat layer to cover the underlying decorative livery layer, the basecoat layer and the surface preparation layer.
