Methods and systems for painting surfaces (especially vehicle surfaces such as exterior aircraft surfaces) are provided whereby an applied basecoat layer may be treated with plasma (e.g., a non-thermal atmospheric pressure plasma) or laser radiation so as to form a treated basecoat layer which exhibits a decreased contact angle and an increased wetting energy as compared to the contact angle and wetting energy of the basecoat layer which is untreated. At least one inkjet printed color layer may be applied onto the treated basecoat layer followed by the application of a clearcoat protective layer over the one or more inkjet printed color layers.

A multi-layer coating system includes: (a) a first basecoat layer formed from a first coating composition including a free polyisocyanate and hydroxyl functional polymeric core-shell particles; (b) a second basecoat layer applied over at least a portion of the first basecoat layer, the second basecoat layer formed from a second coating composition including carboxylic acid functional polymeric core-shell particles; and (c) a topcoat layer applied over at least a portion of the second basecoat layer, the topcoat layer formed from a coating composition including least one free polyisocyanate having a weight average molecular weight of less than 600 g/mol and at least one film-forming resin in which an amount of free polyisocyanate having a weight average molecular weight of less than 600 g/mol is greater than 5 weight %, based on the total resin solids of the coating composition that forms the topcoat layer.

A coated substrate for an electronic device can include a substrate, a basecoat layer on the substrate, and an anti-fingerprint topcoat layer on the basecoat layer. The substrate can include a metal or metal alloy. The basecoat layer can include pigment particles and a first one-part thermally cured polymeric resin. The anti-fingerprint topcoat layer can include a second one-part thermally cured polymeric resin and an anti-fingerprint material. The anti-fingerprint material can include a fluoropolymer, a silane, or a combination thereof. The basecoat layer can be cured before applying the anti-fingerprint topcoat layer on the basecoat layer.

Disclosed herein is a surface repair and livery printing system and method. The method includes receiving an aircraft part having an altered surface image and selecting a repair process from one of a paint repair process, a decal repair process, or an inkjet repair process, based on characteristics of the altered surface image. The method also includes applying paint to the surface over the altered surface image. In response to selecting the decal repair process, the method includes printing a first image on a decal based on the characteristics of the altered surface image and a second image associated with the altered surface image and a step of applying the decal to the surface at least partially over the altered surface image. In response to selecting the inkjet repair process, the method includes performing the inkjet repair process to at least a portion of the surface based on the characteristics of the altered surface image.

Disclosed herein is a surface preparation and livery printing system and a method of preparing a surface and printing a livery. The method includes preparing a surface of an aircraft part in a first processing booth to form a prepared surface of the aircraft part. The method also includes transporting the aircraft part to a second processing booth being adjacent to the first processing booth upon completion of preparing the surface. The method further includes applying a livery to the prepared surface of the aircraft part in a second processing booth and upon completion of applying the livery, transporting the aircraft part to a third processing booth being adjacent to the second processing booth. The method still further includes applying a clearcoat over at least the livery applied to the prepared surface of the aircraft part in a third processing booth.
