Estes Red Max Build, Part 9, Touch-Up Paint - Tip

I didn't get an opaque red on the trailing edge of one fin. The decals were already placed when I noticed it.
Not wanting to mask and re-shoot red paint, I did an unnoticeable touch-up.

A small plastic mixing cup was lined with a sandwich bag. Press the bag all the way down into the cup. Do your best to roll it over the sides. Spray the red paint close and into the cup

Dip a Q-tip into the paint. There's probably too much paint on the Q-tip so roll some of the excess off on a paper towel.

Simply roll, (don't brush) the paint onto the edge.
A rounded surface like this is easiest to touch-up. Flat surfaces (fin faces and body tubes) are harder to fix.
The Rustoleum 2X paints I use have more pigment than other brands and should only require one coat to cover this area.

In the picture you can see half of the fin has been touched up. The edge above the Q-tip still needs paint.
