Estes Super Orbital Transport Build, Kit #7314, Part 18, Nozzles & Paint

I painted the engine tubes off the model so I could get white paint into the housings and full coverage on the tubes.

These were spray painted Gloss White and allowed to dry.

The tubes were lifted off the tape and turned to get the other side covered.

You could do this with a brush and black paint - 

I went the easy route blackening the inside rear half of the engine tubes with a medium point Sharpie.

Note the tube edge is still white. 

Before spray painting the Glider nozzle,

TIP: Lightly sand off any ink lines off the edges.

This ink could bleed through the final white paint.

Here's the nozzle assembly taped down to a piece of scrap cardboard for Gloss White spraying.
