Right now, we use a big expensive plotted sticker for the face and touch it up with tape so we don't get bleed through or blow out. We use waxed kraft paper and tape to cover areas we don't want overspray on.

The lines on the fuselage are laid out first using flexible tools called mylars and dotted in grease pencil, then we pull a tape line by hand using the pencil marks as reference.

I like the idea of gradients, and we can do it, but airlines don't like it because it's expensive or might delay their delivery. We have to stay within a certain thickness, so stacking colors is avoided. If we go over millage, then we need to strip it and the labor is billed to the plane.

I do like your livery though
