How do get a camouflage effect?
Cover the plane in the base colour (tape or heat shrink film) and then apply patches cut from heat shrink film or sign writing vinyl (but not the polypropylene tape – it is hard to cut to shape). Alternatively, you can colour in the camouflage patches with a permanent marker. Permanent markers are useful for drawing in landing gear, panel lines, cockpit structure, exhausts and insignia. Wash the areas where you are marking, with warm water with some dishwashing detergent in it, rinse with clear water and dry well before using a waterproof marker, for example an Artline 70 High Performance fine point tip works well. Insulation tape is easy to cut to shape for lettering and invasion stripes.
