That's coming along nicely Frank. I have never used precut stencils before but that sure looks like the way to go
Those stencils are vinyl and easy to apply. The adhesive is a little aggressive so you have to be sure the paint is well cured so it doesn't come up when the stencils are removed.
The first times I used the stencils, on a Flying Tigers P-40B and a Bell P-400 Airacobra, I let the paint cure for a week and applied Tamiya Clear Gloss before applying the stencils. Some of the enamel paint still came up. On the Spitfire, it is painted with Mr. Color acrylic paint and after curing for 24 hours, it took the stencils very nicely. No paint came up.
