510013 - External Metallic Surfaces - Polishing

(e) Polish heavily oxidized surfaces with NuShine II-F7 (Nuvite F7), using a rotary buffer with wool or cotton pad.

(f) Polish dull surfaces with NuShine II-G6 (Nuvite G6), using a rotary buffer with wool or cotton pad.

(g) Polish surfaces for routine maintenance, with NuShine II-C (Nuvite C), using an orbital polisher or cyclo-orbital polisher with a clean terry cloth (preferably 2 x 3 feet section) (0.56 square meters) wrapped around pads. See Table 1.

(h) Continue to polish surface until polish material starts to dry and surface begins to shine.

(i) Remove excess polish by wiping with a clean, lint free wiper.

(j) Wipe with terry cloth and continue until material is free of residue.

(k) Polish surface with NuShine II-S (Nuvite S) using a cyclo-orbital polisher with a clean terry cloth (preferably 2 x 3 feet section) (0.56 square meters) wrapped around pads.

(l) Continue to polish surface until polish material starts to dry and surface begins to shine.

(m) To obtain a final luster appearance, hand polish in span direction using NuShine II-S (Nuvite S) or Rolite AP-300 using clean terry cloth.

(n) To maintain final luster appearance, routinely polish leading edge (bright work) with NuShine II-S (Nuvite S) or Rolite AP-300.

NOTE: After surface undergoes final polish with NuShine II-S (Nuvite S) or Rolite AP-300, avoid soap or solvent wiping which can remove polish film.

(2) Recommendations For Improved Corrosion Inhibition and Polish Longevity

(a) Avoid use of detergents that are highly alkaline or those containing ammonia on polished metal.

(b) Routinely hand dry surface to remove moisture or condensation. This will help to eliminate watermarks and remove dissolved minerals.

NOTE: Most dirt, debris and bugs on a properly polished surface can be removed by wiping with a clean rag and water. Detergents are normally not needed.

(3) Xzilon Protection Treatment

CAUTION: THE XZILON 3 MATERIAL SHALL BE APPLIED WITHIN A 12 HOUR WINDOW

AFTER COMPLETING POLISHING OPERATION. KEEP ALL MATERIAL FROM

BEING EXPOSED TO FLOOR AND SHOP CONTAMINATION.

(a) Cleaning Polished Metal Prior to Xzilon 3 Application

WARNING: ISOPROPYL ALCOHOL IS TOXIC AND FLAMMABLE. DO NOT USE

NEAR SPARKS, FLAMES OR HEAT SOURCES. WEAR APPROPRIATE

PROTECTIVE CLOTHING, SOLVENT RESISTANT GLOVES AND EYE

PROTECTION. AVOID SKIN CONTACT. AVOID BREATHING FUMES. IF

YOU GET ISOPROPYL ALCOHOL ON YOUR SKIN, WASH WITH SOAP

AND WATER. IF YOU GET ISOPROPYL ALCOHOL IN YOUR EYES,

IMMEDIATELY FLUSH WITH COLD WATER, LIFTING THE EYE LIDS

TO FLUSH THE INSIDE SURFACES OF THE LIDS AND THE ENTIRE

AREA OF YOUR EYE. FLUSH FOR 15 MINUTES AND SEEK MEDICAL

510013 - External Metallic Surfaces - Polishing

(1) Use Granitize Aviation XG-5 hard surface cleaner concentrate diluted to 1 part XG-5 to 3 parts distilled water in a spray bottle or 100% isopropyl alcohol.

NOTE: This is the most important application process.

(2) Wipe with a clean H-73 synthetic cloth.

NOTE: Cloth is supplied in Granitize Aviation X-3500-18 kit.

(3) Repeat Step B(3)(a)1 thru Step B(3)(a)2, as required, ensuring surfaces are clean from all polishing residue.

(b) Apply Xzilon 3 as follows:

NOTE: Temperature during application should be between 45 - 90°F (7 - 32°C).

No visible moisture is allowed during the process. Keep Xzilon 3 container sealed when not in use. Product will attract moisture and harm formulation effectiveness defeating molecular adhesion properties. Shake bottle well repeatedly during application process. Use product sparingly.

(1) Apply a small amount of Xzilon 3 (approximately one thimble full) to H-38X red felt applicator.

(2) When working an area of 2 x 2 feet (0.5 square meters), apply a thin film of Xzilon 3.

Do not allow Xzilon 3 to dry.

(3) Wipe treated area with provided H-73 clean synthetic cloth until all wet film is buffed and no longer visible. Rotate H-73 cloth out, as necessary, when absorbency decreases.

NOTE: Cloth is supplied in Granitize Aviation X-3500-18 kit.

(4) Repeat Step B(3)(b)1 thru Step B(3)(b)3 until all subject areas are treated.

(5) Allow 30 - 45 minutes between coats.

NOTE: Three coats are mandatory for maximum protection and 12 hour cure time is mandatory after final coat is applied before flight.

(c) Detect presence of Xzilon 3 as follows:

(1) Use common 2 inch (50.8 mm) wide masking tape in a 6 inch (152.4 mm) length.

(2) Tear two pieces off roll of tape. Make a lap over 1 inch (25.4 mm) tab at end of both pieces of tape.

(3) Firmly press tape on subject treated area versus an untreated area.

(4) Pull tape back slowly at a 90° angle to surface.

(5) A noticeable ease in resistance will take place on a treated surface versus an untreated surface.

(d) Evaluate reflectivity of polished surface as follows:

(1) Hold mirror tag 12 inches (0.30 meters) from polished surface.

(2) If it is possible to read mirror tag wording in polished surface reflection, surface condition shall be considered acceptable. See Figure 1.

(f) Polish dull surfaces with NuShine II-G6 (Nuvite G6), using a rotary buffer with wool or cotton pad.

(g) Polish surfaces for routine maintenance, with NuShine II-C (Nuvite C), using an orbital polisher or cyclo-orbital polisher with a clean terry cloth (preferably 2 x 3 feet section) (0.56 square meters) wrapped around pads. See Table 1.

(h) Continue to polish surface until polish material starts to dry and surface begins to shine.

(i) Remove excess polish by wiping with a clean, lint free wiper.

(j) Wipe with terry cloth and continue until material is free of residue.

(k) Polish surface with NuShine II-S (Nuvite S) using a cyclo-orbital polisher with a clean terry cloth (preferably 2 x 3 feet section) (0.56 square meters) wrapped around pads.

(l) Continue to polish surface until polish material starts to dry and surface begins to shine.

(m) To obtain a final luster appearance, hand polish in span direction using NuShine II-S (Nuvite S) or Rolite AP-300 using clean terry cloth.

(n) To maintain final luster appearance, routinely polish leading edge (bright work) with NuShine II-S (Nuvite S) or Rolite AP-300.

NOTE: After surface undergoes final polish with NuShine II-S (Nuvite S) or Rolite AP-300, avoid soap or solvent wiping which can remove polish film.

(2) Recommendations For Improved Corrosion Inhibition and Polish Longevity

(a) Avoid use of detergents that are highly alkaline or those containing ammonia on polished metal.

(b) Routinely hand dry surface to remove moisture or condensation. This will help to eliminate watermarks and remove dissolved minerals.

NOTE: Most dirt, debris and bugs on a properly polished surface can be removed by wiping with a clean rag and water. Detergents are normally not needed.

(3) Xzilon Protection Treatment

CAUTION: THE XZILON 3 MATERIAL SHALL BE APPLIED WITHIN A 12 HOUR WINDOW

AFTER COMPLETING POLISHING OPERATION. KEEP ALL MATERIAL FROM

BEING EXPOSED TO FLOOR AND SHOP CONTAMINATION.

(a) Cleaning Polished Metal Prior to Xzilon 3 Application

WARNING: ISOPROPYL ALCOHOL IS TOXIC AND FLAMMABLE. DO NOT USE

NEAR SPARKS, FLAMES OR HEAT SOURCES. WEAR APPROPRIATE

PROTECTIVE CLOTHING, SOLVENT RESISTANT GLOVES AND EYE

PROTECTION. AVOID SKIN CONTACT. AVOID BREATHING FUMES. IF

YOU GET ISOPROPYL ALCOHOL ON YOUR SKIN, WASH WITH SOAP

AND WATER. IF YOU GET ISOPROPYL ALCOHOL IN YOUR EYES,

IMMEDIATELY FLUSH WITH COLD WATER, LIFTING THE EYE LIDS

510013 - External Metallic Surfaces - Polishing

(1) Use Granitize Aviation XG-5 hard surface cleaner concentrate diluted to 1 part XG-5 to 3 parts distilled water in a spray bottle or 100% isopropyl alcohol.

NOTE: This is the most important application process.

(2) Wipe with a clean H-73 synthetic cloth.

NOTE: Cloth is supplied in Granitize Aviation X-3500-18 kit.

(3) Repeat Step B(3)(a)1 thru Step B(3)(a)2, as required, ensuring surfaces are clean from all polishing residue.

(b) Apply Xzilon 3 as follows:

NOTE: Temperature during application should be between 45 - 90°F (7 - 32°C).

No visible moisture is allowed during the process. Keep Xzilon 3 container sealed when not in use. Product will attract moisture and harm formulation effectiveness defeating molecular adhesion properties. Shake bottle well repeatedly during application process. Use product sparingly.

(1) Apply a small amount of Xzilon 3 (approximately one thimble full) to H-38X red felt applicator.

(2) When working an area of 2 x 2 feet (0.5 square meters), apply a thin film of Xzilon 3.

Do not allow Xzilon 3 to dry.

(3) Wipe treated area with provided H-73 clean synthetic cloth until all wet film is buffed and no longer visible. Rotate H-73 cloth out, as necessary, when absorbency decreases.

NOTE: Cloth is supplied in Granitize Aviation X-3500-18 kit.

(4) Repeat Step B(3)(b)1 thru Step B(3)(b)3 until all subject areas are treated.

(5) Allow 30 - 45 minutes between coats.

NOTE: Three coats are mandatory for maximum protection and 12 hour cure time is mandatory after final coat is applied before flight.

(c) Detect presence of Xzilon 3 as follows:

(1) Use common 2 inch (50.8 mm) wide masking tape in a 6 inch (152.4 mm) length.

(2) Tear two pieces off roll of tape. Make a lap over 1 inch (25.4 mm) tab at end of both pieces of tape.

(3) Firmly press tape on subject treated area versus an untreated area.

(4) Pull tape back slowly at a 90° angle to surface.

(5) A noticeable ease in resistance will take place on a treated surface versus an untreated surface.

(d) Evaluate reflectivity of polished surface as follows:

(1) Hold mirror tag 12 inches (0.30 meters) from polished surface.

(2) If it is possible to read mirror tag wording in polished surface reflection, surface condition shall be considered acceptable. See Figure 1.

510013 - External Metallic Surfaces - Polishing

NOTE: This process is applicable to exterior metallic surfaces to attain a high luster (glossy) finish, to include leading edges of wing, winglets, vertical stabilizer, horizontal stabilizer, engine pylons, APU exhaust fairing, engine nacelle surfaces (e.g., nose cowl, thrust reversers) as well as other metallic exterior components requiring normal routine maintenance and cosmetic polishing. The application of Xzilon 3, as an additional protective layer to inhibit corrosion, is required by Gulfstream for aircraft operating in corrosion prone environments.

If pitting corrosion is present and material removal is beyond engineering blueprint tolerances, contact Gulfstream Customer Support for further assistance.

510013 - External Metallic Surfaces - Polishing

(1) Reference(s)

• Safe Ground Maintenance Procedure, 20-00-00, Maintenance Practices

(2) Aircraft Preparation

(b) Clean exterior metallic surfaces prior to polishing with lint free cloth and an approved cleaning solvent. See Table 2.

(c) Cover surrounding area with protective covering (e.g., paper or plastic) secured in place with masking tape.

(d) Cover any opened areas to prevent dust and compound buildup during process which may damage internal structure.

B. Procedure

WARNING: DO NOT ALLOW POLISHING COMPOUND ON SKIN, IN MOUTH OR IN EYES. USE

APPLICABLE GLOVES, EYE PROTECTION AND FACE MASK. USE POLISHING

COMPOUND ONLY IN AN AREA THAT HAS A GOOD AIRFLOW. DO NOT BREATHE

FUMES FROM POLISHING COMPOUND. IF POLISHING COMPOUND COMES INTO

CONTACT WITH SKIN, EYES OR MOUTH, IMMEDIATELY FLUSH WITH WATER

FOR AT LEAST 20 MINUTES AND GET MEDICAL AID.

CAUTION: NO SANDING, CHLORINATED SOLVENTS OR CHLORINATED CLEANERS SHALL

BE USED.

PROTECT SURROUNDING SURFACES THAT ARE NOT BEING POLISHED DURING

THIS PROCESS.

(1) Polishing Exterior Metallic Surfaces

(a) Thoroughly wipe entire surface with a detergent (Arm & Hammer Plus OxiClean or equivalent) or approved cleaning solvent using a lint free wiper. See Table 2.

(b) If performing 12 month polishing, proceed to Step B(1)(d).

NOTE: Polishing and Xzilon application must be performed at least once every 12 months.

(c) Evaluate reflectivity of polished surface as follows:

(1) Hold mirror tag 12 inches (0.30 meters) from polished surface.

(2) If it is possible to read mirror tag wording in polished surface reflection, surface condition shall be considered acceptable. See Figure 1 and proceed to Step C(1).

(d) Determine method of polishing from the following:

(1) For polishing heavily oxidized surfaces, proceed to Step B(1)(e).

(2) For polishing dull surfaces, proceed to Step B(1)(f).

(3) For routine maintenance polishing, proceed to Step B(1)(g).

(4) If only Xzilon application is needed, proceed to Step B(3).
