4. Paint the bottom of the airplane first including the bottom of the horizontal tail surfaces. Starting at the
root and working outward, spray chordwise. Work up the fuselage and allow the spray to cover the
sides. Work all the way up to the engine. Spray the bottom of the wing. Each painter should start at the
root and work toward the tip, spraying chordwise.
5. Lower the tail of the airplane enough to allow the top of the fin to be reached. When spraying the top
of the fuselage, tilt the gun so the overspray will be ahead of the area being painted and the new
material will wipe out the overspray. Spray primer across the fuselage, vertical and horizontal tail
surfaces and the wing.

POLYURETHANE PAINT SAFETY
—WARNING—
Polyurethane paint may be dangerous to your health. If safety
precautions are not followed, serious injury could result.
1. During transit and storage check for signs of a bulging can, emission of other than normal odor or, or a
change in the resin from a clear to cloudy state. This results in the slow buildup of carbon dioxide
which could cause the can to burst. Any cans found to be defective should be removed and disposed
of.
2. Ensure adequate ventilation and wear an appropriate breathing protection face mask when painting.
3. Polyurethane paints can produce irritation of the skin, eyes, and respiratory tract during mixing and
application. Allergic sensitization of personnel exposed to the vapors and mists produced during spray
application may occur and cause difficulty in breathing, dry cough, and shortness of breath. Individual
susceptibility appears to be a controlling factor. Once sensitized, many workers cannot tolerate even a
minimum subsequent exposure and must thereafter avoid work areas where such exposure could occur.
4. Production type mixing and spray painting operations should be conducted in specially designed,
exhaust-ventilated areas, using personal protective equipment as follows:
a. Fitted, double cartridge organic vapor respirator with fresh cartridges inserted daily.
b. Solvent-resistant gauntlet style gloves.
c. Safety goggles.
5. Painters must be fully clothed with collars buttoned and sleeves taped at the wrist.
