Estes Saturn V #1969 Build, Part 37, Wrap Reduction Black Outlines Part 2

Before proceeding -
Please understand this method is not perfect. If you aren't careful with the spray can, paint can still sneak into the low ribs of the corrugation.
I still had quite a bit of touch-ups to do after the masking tape was lifted. The ink outlines help get a sharper line.
If you don't have a steady hand - go with a different method. I don't want to hear from anybody telling me: "You ruined my rocket!"

TIP: One the first pass, draw a line just over the high raised rib, not down into the corrugated rut.
On the second pass connect the small dashes from below (or above) depending on the line.

Enlarge this picture - 
On the left is the first pass just on the raised ribs, it looks like a dashed line.
On the right is the recess of the corrugation. I've filled in the line from the rib recess "going up" to the previous dashed line.

Notice the low rut fill line is started about 1/16" below and goes up to match the upper dashed straight line. You don't have to go as wide as I did in the third picture shown below -


I used a regular fine point pen to designate the upper and lower black bands. I'll go back and widen the line on the ribs so these join in the center with the ultra fine point pen.
Notice I didn't go all the way to the top and bottom of the shroud - this pen point is too wide. The corners will be drawn with the Ultra fine point Sharpie.




You shouldn't go this wide with the Sharpie ink border, a little over 1/16" wide should do it. As I found out, the Sharpie ink isn't as black as the sprayed paint. This ink looks a little "blue-black" under direct sunlight. In the end I had to go back and brush paint closer to the border line.

Here's the color border lines, ready for an easier mask with the black spray paint.

  1. Did you ever consider brush painting the entire black sections, following the Sharpie outline? I am trying to weigh the pros and cons of the time spent masking, spraying, and eventually touching up anyway, to just outlining with the Sharpie and brush painting the entire sections. Thanks for any insight you may have.

    1. Hi Gary,
      The corrugation areas should hide the brush lines pretty well, the smooth surface areas should be sprayed.
