Estes Photon Probe #3026 Build, Part 10, Paint and Masking
Mentioned earlier, the fins are centered on the strips. The strip isn't much wider than the small fins. A very small fillet was applied to the upper fin sides.
It took quite a bit of fine sanding to get the fillet areas smooth. This one required two base coats of gloss white and sanding in between before a final, wetter coat.
All masking should be as easy as this! If you can't get a clean mask going around a smooth body tube you shouldn't be building rockets.
The older instructions just say to paint it like the face card, no measurements are given for the mask line.
The new instructions tell you to mask 7 1/2" from the bottom and 3 1/4" down from the top of the tube.
