Zinc chromate is often the go-to for the former and the latter is used to give the aircraft a nice shiny look. According to Friese, it takes a 30 person crew seven days, working two and a half shifts, to paint a narrow body aircraft. It also keeps a tremendous shine even after exposure to hard conditions.

But it all breaks down into basically two different kinds of paint: enamel paints and acrylic paints. Modified zinc chromate primer does not adhere satisfactorily to bare metal. Mix the selected topcoat paint that is compatible for the repair. Do not use MEK on nitrocellulose finishes. Old acrylic finishes may be refinished with new acrylic if the old coating is softened using acrylic nitrocellulose thinner before touchup. Acrylic nitrocellulose lacquers adhere poorly to bare metal and both nitrocellulose and epoxy finishes. The process has minimum effect on the surface under the paint because of the plastic medium and relatively low air pressure used in the process. Necessary to prevent corrosion and for an aircraft’s appearance and safe operation, we sell aircraft paints and coatings to government agencies, airlines, MRO’s large-scale aviation businesses and private plane owners.

Allow time for the first coat to flash before applying the second coat. One of the first steps is to identify the paint that needs to be touched up. The toughness of enamel makes it strong enough to handle the conditions to which an aircraft is regularly exposed. Before any chemical stripping can be performed, all areas of the aircraft not being stripped must be protected. Primer is applied first, followed by the topcoat. Touchup may also be used to cover minor topcoat damage, such as scratches, abrasions, permanent stains, and fading of the trim colors.
