Metal Polishing System PROCEDURES - jetstreamproducts.com

1 Metal Polishing Up:When performing bright work it is essential thatyou have the right products, tools and PROCEDURES toachieve the proper results. There are no short cuts! Buff-ing Metal is very physical and dirty work, so, do not wastetime holding a buffer above your head unless you know thejob is being done right the first time. Products requiredareSkai Metal PolishandMirror Image. To help speedup cutting through heavy oxidation, it is recommend useNo. 7 Rubbing Compound, applied over a thin layer ofSkai Metal Polish. Tools will consist of a variable speedbuffer, we recommend the Makita model # 9227C, woolcutting pads and a spur buffing pad cleaner. You will alsoneed 1 dozen shop rags, a container of flour used for ab-sorbing black residue left behind in rivet and screw heads,and two inch, 3M masking tape part #2311.

2 For your com-fort and safety, it is recommend to use ear plugs, safetyglasses, and an :Use a variablespeed buffer like the Makitamodel #9927C. This buffer islight weight and has a rpmrange between 800 and has plenty of power and willnot bog down. The variablespeed will allow you to slowthe buffer down and safelybuff tight areas or set it on high rpm to speed up the buffingprocess when clear of obstacles. Pneumatic buffers arelight weight and do a great job. They offer the most controland are safer for both you and the aircraft . Their disadvan-tage is that they require a high volume, clean source ofcompressed air to operate correctly. So, pneumatic buffersare light weight, easy to control and safer, because there isno chance of electrocution, but you must have a clean,strong and reliable source of compressed Pad:When buffing,use wool cutting pads, 7-1/2inch diameter, 1-1/2 inch pilefor digging out oxidation :When pads become gummedup with polish and will notfluff back up afterspurring, change out to fresh pad.

3 Dirty pads will put deepswirls in the surface of Metal that are difficult to will give your polish job a butchered up look thatwill not be visible until pulled out in the - Buffing Pad Cleaner:As you buff your pad will fillup with polish residue. Padsshould be cleaned frequentlywhen buffing by using a pol-ishing spur. This is done byholding the buffer uprightand pulling the spur throughthe pad while running thebuffer. This will remove polish residue build-up, keepingthe pad clean and allowing your pad to absorb polish fromsurface being polished. This allows the surface being pol-ished to clear to a mirror :Hold spurfirmly, to avoid spur from being jerked out of your hand,and possibly damaging 1: Taping:Using 3 Mtwo inch masking tape, part #2311, tape all painted sur-faces adjacent to Metal beingpolished.

4 Taping will protectthe painted surfaces fromblackpolishresiduethatforms when Polishing not use low quality mask-ing will leave behind a sticky residue, makingclean up considerably more difficult and time :Covering aircraft surfaces with paper or plastic willbe a mandatory requirement by some aircraft only time that it will be a necessary requirement iswhen working on an aircraft that has oxidized paint. Oxi-dized paint will allow the black residue to be absorbeddown into the paint. Chances are the stain will not comeout. When in doubt, do the safe thing and cover the air-craft with paper or 2: Applying Polish:ApplySkai Metal Polishspar-ingly with a damp, clean, soft cloth. Apply polish to a 4 to 6foot sections of leading edge. Buff out each section beforeapplying polish to next : If Metal is heavily oxi-dized, apply a second layer ofNo 7 Rubbing Compoundtothe already applied layer ofSkai Metal Polish.

5 TheNo 7 Rubbing Compoundwill addan aggressive layer or abra-sives which will speed up theprocess of removing heavyoxidation from aluminum 7 Rubbing Com-poundhas been around is a very uniqueproduct when Polishing alu-minum because it willnotleave a cloud in the surface ofthe clears to a mir-ror finish when used withSkai Metal 3: Buffing:Now that this sections of leading edgehas been made ready, it s time to begin Polishing . Using amachine polisher, buff themetal surface until you have aclear reflection of yourself inthe surface of the Metal , freeof all blemishes. Bottoms canbe difficult because you willbe supporting the weight ofthe buffer plus using addi-tional pressure required tocut through oxidation andaccumulations of dried is important thatyoucare-fully follow the previous out-lined PROCEDURES , and areusing the proper tools andproducts to achieve 4: Removing Swirls:Swirls give polished Metal abutchered up or hacked up appearance.

6 Swirls are the endresult of using a buffer. They have the appearance of cattails as you can see in adjoining photo. To remove swirls,use a two to three inch pieceofMirror Imageand applyby hand to the newly pol-ished surface. As you applyMirror Image,a black resi-due will appear and cover thenewly polished Metal a folded micro fiber,towel begin breaking downand removing this residue before it thisprocess, the swirls are being removed from the surface ofthe Metal . As the Metal begins clearing under your microfiber switch to a fresh towel and finish Polishing out themetal surface. You have nowcompleted your first sectionof leading edge. The surfaceof the Metal should be free ofall oxidation, blemishes, bugmarks, and swirls as shown inbottom 5: Applying Flour:To help remove any black resi-due left on the Metal surface, rivets or screw heads, apply asmall amount of household flour to a clean micro fibertowel and rub across flour will ab-sorb any black residue left onthe surface of the :Swirls are removedwhenMirror Imageis beingbroken down and removed asdescribed in step four.

7 If youremove theMirror Imagetoo soon by absorbing it with the flour, you will not achievethe desired : If you have followed all directions up to this point,you will be successfully Polishing Metal . You will need torepeat the first five steps on each section of Metal you pol-ish. The following directions will provide you with helpfulhints that will allow you to safely position yourself and pol-ish the Metal on a Challenger same basicguidelines will be used on other aircraft when Engine Intakes:Once you have finished polishingthe leading edges on the wings, move to the engine in-takes. On the Canadair Chal-lenger aircraft , you will needa pump up stand to positionyourself in front of the engineintakes. It is possible to placea 6 ladder on top of a mat,placed it at the back of thewing to polish the intake. It isawkwardand unsafe due tothe slope at the back of the wing on the , have someone hold the ladder.

8 Always place rub-ber mats down where you will be laying tools down andstanding. Now that you are in position, tape the intake andbegin Polishing . Engine intakes will have heavy accumula-tions of bugs that will require extra attention when you have cut through all oxidation and bug stains,continue with steps four and five. Before you know it, youwill be making your final wipe and inspection and ready tomove on to the engine Engine Cones:Notall Challenger s have the plane does now will standing on top of theengine pylons, you will wantto place a mat down to pro-tect the aircraft as seen in thepicture. Once everything isin position and taped, begin can expect the cones to be oil andcarbon stained. To remove these stains,it will require an additional cut by usingtheNo 7 Rubbing one through five to complete thepolishing of the engine Leading Edges On Tail:You will need a scissor liftto reach the vertical and horizontal leading edges on thetail of the aircraft .

9 Most flight departments that operate thelarger corporate jets will ownor have access to a scissor usually have no prob-lem allowing you to use theirlift when they have requestedyour detailing services. Theleading edges on the tail willbe no different than the rest ofthe Metal on the aircraft . Fol-low the detailed PROCEDURES outlined in steps one throughfive and you will have no problems finishing the brightwork job on this Challenger or any other caution when operat-ing the scissor lift around air-craft. We recommend using aspotter below the lift whenpositioning the lift next to anaircraft. When Polishing thebottom section of the verticalleading edge, you will berequired to stand on top ofthe fuselage to position yourself for buffing. For personalsafety, we recommend using a body harness securelylatched to the lift with a safety Clean Up:Buffing Metal makes quite a buffing pads will give off a blackwool fuzz that will cover the aircraft andhangar floor.

10 You will need to dust offthe aircraft using a towel wrappedaround a squeegee as shown in pictureon you will not be cleaning theaircraft after Polishing the brightwork,we recommend covering the aircraftwith plastic or paper before floor Clean-Up:You will need to sweep the han-gar floor using a large push broom. Take caution not totrack this black fuzz into the aircraft or hangar offices. Ifyou are providing an aircraftdetailingservice,sweepingthe hangar floors will not be anoption. cleaning up your messshows the customer that youprovide a responsible servicethat leaves their facility look-ing as good if not better thanwhen you
