I think those are stenciles. Petes stuff is dots that stick to the airplane. See instructions from wow planes on how to use them
User Instructions:
1. Draw the panel lines on the model with pencil or pen.
2. Peel a rivet stencil from the sheet.
3. If some of the dots do not release, stick and peel them off on a sheet of glass.
4. Lay the stencil over the line and rub with finger to make contact with surface.
5. Dab undiluted Titebond Wood Glue into the holes.
6. Before glue hardens, slowly lift tape off the surface at 90 degrees.
7. Allow glue to dry.
Here are the application photos from my 47. Now the wow planes stencel would have been great for my tf p51 i used wood glue on.
