Orange Line is a lacquer type, and that is exactly what sets it apart: the film is thinner, harder and far more tolerant of masking tape and careful sanding. Sets from this line are assembled mostly around aircraft schemes across several eras, from early wartime camouflage to modern low-visibility greys.
Plan for the matching lacquer thinner and a bench you can ventilate properly, because the fumes here are stronger than with water-thinnable colours.
Lacquer paints flash off quickly and form a coherent layer that tape cannot soak into and will not lift when it comes away. On multi-colour camouflage with hard edges that is a real advantage, because you can mask soon after the previous shade. The thin film also leaves engraved panel lines readable, which matters to anyone who picks out the seams afterwards.
Thin only with the lacquer thinner from the same line. Lacquer types tolerate generous thinning, so they spray well at lower pressure in light passes. An airbrush setup with extraction is a genuine advantage, ideally with a gun chosen from the spray guns category.
Work in a ventilated space and wear a respirator. Strip and clean the gun the same day, because cured lacquer is far harder to remove than acrylic. Suitable products sit among the thinners and cleaners, including lacquer cleaner for flushing the cup between shades.
A lacquer base is a dependable ground for acrylic and oil weathering, because the solvents in those products will not bite into it. Going the other way, lay the first lacquer pass very lightly over acrylic so the colour underneath is not lifted.
Subjects run mainly to aircraft kits and helicopter kits. Other sets from the same brand are gathered in Hataka paint sets.
