Hello Michael. I used Oracal Oramask 813 stencil vinyl. I got 12 1 foot square sheets on Amazon for I think $20. It is semi rigid but malleable enough to curve around things like fuselage sides. I used painters tape for some markings too, but I find for the larger markings the stiffer vinyl is a bit better.
Another product I found invaluable was trasnfer tape. Any kind will do. But this allows you to transfer the stencil and align and realign different parts.
The end of this thread goes over what I did and how it worked
If you have any questions let me know!
I’ve found it versatile. The markings on this archer, ME-262 and KV-1 were also masked with the cricut
