Estes Plasma Probe Build Part 17 Fin Masking
This is why I left the small tips of the forward fins square, it make for an easier mask.
Masking around a rounded leading edge takes a lot of small pieces of tape.
Here I've just did one wrap over all four fin tips.
A long piece of tape goes down all the root edges.
Try to center the tape line down the middle of the rounded fillet.
Along the back the overhanging root edge tape was trimmed using the body tube edge as a guide.
Use a sharp knife and don't cut into the white paint on the edge.
Masking tape strips went down the open middle areas between the root edge masks.
Around the top was two wraps of paper.
All the edges got a light rubbing over with a sharpened dowel to seal the edges.
