| WHY IS BUTYRATE DOPE SAFER TO USE THAN NITRATE DOPE? | IT IS MUCH LESS FLAMMABLE. |
| WHAT ARE THE TWO TYPES OF DOPE USED FOR FABRIC FINISHES? | CELLULOSE NITRATE AND CELLULOSE ACETATE BUTYRATE. |
| WHAT IS THE APPEARANCE OF BLUSHING PAINT FINISH? | CHALKY OR CLOUDY |
| WHAT FINISHING DEFECT IS THE RESULT OF A PAINT ROOM TEMPERATURE THAT IS TOO WARM? | PINHOLES OR BLISTERS. |
| WHAT CAUSES DOPE TO BLUSH? | HIGH HUMIDITY, MOISTURE IN THE SPRAY SYSTEM, OR APPLICATION OVER A DAMP SURFACE. |
| WHAT FACTORS CAUSE SPRAY PAINT SAGS AND RUNS? | INADEQUATE SURFACE PREPARATION OR PAINT SPRAYED ON TOO THICKLY. |
| WHAT COMPONENTS OR PARTS OF THE AIRFRAME MUST BE PROTECTED FROM DAMAGE WHEN USING PAINT STRIPPER? | WINDSHIELDS AND WINDOWS, PLASTICS, COMPOSITES, SYNTHETIC RUBBER, AND FABRICS. |
| WHAT IS THE FUNCTION OF ZINC-CHROMATE OR WASH PRIMERS? | PRIMERS SERVE TO INHIBIT CORROSION AND PROVIDE A GOOD BOND BETWEEN THE METAL AND THE TOPCOATS. |
| NAME SEVERAL COMMON TYPES OF PAINT USED ON AIRCRAFT. | ZINC-CHROMATE AND WASH PRIMERS, SYNTHETIC ENAMELS, ACRYLIC LACQUER, AND POLYURETHANE. |
| WHAT IS THE PROPER THINNER TO USE WITH ZINC-CHROMATE PRIMER? | TOLUENE. |
| WHAT HEALTH AND SAFETY PRECAUTIONS MUST BE OBSERVED WHEN USING THE TOXIC SOLVENTS AND THINNERS THAT ARE PART OF MODERN FINISHING SYSTEMS? | RESPIRATORS AND/OR MASKS MUST BE WORN WHEN SPRAYING FINISHES. |
| IF SPRAY PAINTING DUST CAUSES A SURFACE TO APPEAR DRY AND ROUGH, WHAT ARE THE MOST LIKELY CAUSES? | TOO MUCH AIR PRESSURE OR THE SPRAY GUN IS TOO FAR FROM THE SURFACE BEING PAINTED. |
| WHAT CAUSES "ORANGE-PEEL"? | SPRAY PRESSURE TOO HIGH, USE OF A THINNER THAT DRIES TOO FAST, COLD TEMPERATURES, OR A DAMP DRAFT OVER THE SURFACE. |
| WHAT REGULATION GOVERNS THE APPLICATION OF THE REGISTRATION NUMBERS TO AIRCRAFT REGISTERED IN THE UNITED STATES? | FAR PART 45. |
| OTHER THAN APPEARANCE, WHAT IS ANOTHER REASON FOR TOUCHING UP PAINTED SURFACES? | REDUCTION OR ELIMINATION OF GENERAL CORROSION PROBLEM. |
| WHAT REFERANCE SHOULD BE USED TO DETERMINE IF A CONTROL SURFACE MUST BE CHECKED AND/OR REBALANCED AFTER PAINTING? | THE MANUFACTURER'S SERVICE MANUAL. |
| WHAT WOULD BE THE EFFECT IF DOPE WAS USED OVER PAINT OR ENAMEL? | THE DOPE TENDS TO DISSOLVE THESE MATERIALS. |
| WHAT ARE THE THREE MOST COMMONLY USED METHODS OF APPLYING PAINT? | DIPPING, BRUSHING, AND SPRAYING. |
| WHAT IS THE EFFECT ON PAINT FINISHES IF TOO MUCH DRIER IS ADDED TO THE PAINT? | THE PAINT FILM WILL BE BRITTLE AND TEND TO CRACK AND PEEL. |
| WHAT PAINT SYSTEM(S) MAY BE USED WITH EPOXY TOPCOATS? | ANY PAINT SYSTEM IN GOOD CONDITION. |
