At the risk of being a smartass, which is not my intent, try painting something camo and it will start to make sense very quickly. Painting camo is a multi-stage process that adds MANY steps not necessary for a single color paint job.
While I understand the process in a factory setting may be a bit different, if it’s actual paint (not a wrap) the general “typical” process is paint the whole thing with the base color; when dry mask and spray first accent color; when dry mask and spray second accent color; continue until all colors complete (typically 3 to 5); when done with colors buff to smooth the tape lines; clear if you’re clear coating. If you bought a pattern (like Mossy Oak) you don’t have to cut the templates for masking but you do have to pay for them. If your making your own pattern you don’t have to buy the masking templates but you do have to cut them yourself.
Yes, there are other methods, such as sponge painting, but the backyard redneck shortcuts (some of which produce decent results) aren’t what’s going on here with the Kubota product. Kubota may have robots doing the spraying. Even if they do, hard to believe they’re spraying a camo pattern with crisp, clean lines without templates.
It’s quite a bit faster and easier to shoot a single color.
