Yes! The sharpie-effect is nutty, but in original it looks like a kid got loose with his #2 Dixons and scribbled about. They look like squirrely mistakes or grafitti-accidental. Montana spray cans have a good looking webbing effect, saves the time and hassle to do it the old fashioned way and have a messy and inconsistent result.
I'm not sure I'd restore it 100% authentic. The cabinet paint would be the same, sans spider webbing. I'd choose some different lights, especially blinkers, and add some minor, reversible, touches to the plastics.
NOW is, in my mind, the ONE Gottlieb that fell short of its design potential, and I'd like to improve on it and take it to where it should have been. You'll see when I post photos in future. I believe it was a continued attempt at a girly-machine, yet was kind of abandoned after most work done to design. After NOW, Gottlieb went solidly and unabashedly into the MAN-MACHINE MODE of guns, babes, breasts, billiards, bars and brawn.
The only other machine I would consider changing is KING KOOL/ROCK. That cabinet color... why? I think the Bazooka-Joe pink of Flying Carpet is interesting and admirable, but the dingy purple-grey of KING KOOL was like a wrong turn in cabinet design choices. No other cabinets make a blip on my sensibilities like KING KOOL. 1971-2 was a period of shifting gears inside the Gottlieb design crew, and you can see their errors clearly in some of the earliest attempts at becoming "hip" and "with it" as they struggle to appeal to a different audience... and ultimately succeeded beyond competition.
