Nitrate and butyrate
What finishing defect is the result of a paint room temperature that is too warm
Pinholes or blisters
What causes dope to blush and how can it be prevented
High humidity, moisture in the spray system, or application over a damp surface can be eliminated by heating the room to decrease humidity or by using a blush retarding thinner to increase the drying time
What factor cause spray paint sags and runs
Poor surface preparation or paint sprayed on too thickly
What components or parts of the airframe must be protected from damage when using paint stripper/ remover
Windshields and windows, plastics, composites, synthetic rubber, and fabrics
What is the function of zinc-chromate primer
Prevent corrosion and provide a good bond between the metal and the topcoats
Name several common types of paint used on aircraft

What health and safety precaution must be observed when used the toxic solvents and thinners that are part of modern finishing systems
Respirators and mask must be worn when spraying finishes
What causes orange peel
Incorrect spray setting, incorrect air pressure, incorrect paint viscosity, and holding the gun too far from work
What regulation governs the application of the registration number to aircraft registered in USA
FAR Part 45
Other than appearance what is another reason for touching up painted surfaces
Reduce or eliminate corrosion problems
What reference should be used to determine if a control surface must be checked or rebalanced after
The manufactures service manual
What are the three most commonly used method of applying paint
Dipping, brushing, and spraying
What is the effect on paint finishes if too much drier is added to the paint
