Cellulose nitrate
Cellulose acetate butyrate.
What is the appearance of a blushing paint finish?
Chalky.
Cloudy.
What finishing defect is the result of a paint room temperature that is too warm?
Pinholes.
Blisters.
What causes dope to blush?
High humidity.
Moisture in the spray system.
Application over a damp surface.
What factors cause spray paint sags and runs?
Inadequate surface preparation.

If spray painting dust causes a surface to appear dry and rough, what are the most likely causes?
Too much air pressure.
Spraygun is too far from the surface being painted.
What causes orange peel?

Damp draft over the surface.
What regulation governs the application of the registration numbers to aircraft registered in the United States?
FAR part 45
