Please let me know your thoughts and suggestions. DuPont Technical Page Sherwin-Williams Remove the paint: Thoroughly wash the plane with a wax free soap, especially landing gear and other areas which may have grease or oil residue.

This will improve the performance of the strippers. Remove: Control surfaces Inspection panels Fairings Moldings Bag and mark the fasteners so you know which type went where later- even if you are replacing them. I like to take cell phone photos of everything during disassembly. Cover windows with aluminum foil and edge with foil tape.

This edge will be stripped separately later. Also cover with foil and foil tape:. Reason: changed order of events added Berson comments. That's quite a detailed checklist, here is my single comment: I never used any fill primer on a metal airplane yet, seems to me just added weight and cost.

But if you do use fill primer what is it? The epoxy primer should be the first coat. Thanks - That's why I posted the checklist. I found the fill primer note on a painter's website. They used high solids sandable primer in areas needing work such as hail dents and followed it up after the work with the epoxy primer just before painting.

That would mean you would need to work really quick or face sanding the epoxy primer after the 36 hour mark.

All of the paint manufacturers instruct that after the primer is applied, the paint should be applied within a time limit or you need to sand for best adhesion. Best of luck, Wes N78PS. Thanks - I updated the post - in blue - moving the epoxy primer to be applied first to the entire plane and then a sandable primer over that per Sherwin-Williams in areas that need it.

I have some very light hail dents so I will probably apply the sandable primer to the top of my wing and some body filler. Anyone know where we can buy commercial aircraft stripper? I heard "Aircraft" strippers have corrosion control properties not found in other strippers.

Aircraft stripper - I think that I have seen it at Pep Boys. Your local auto paint supplier will likely stock it. Airplanes and custom autos are really the applications for a quality paint remover. I will note that I am told that not all brands of stripper are effective with all types of paint. I think that I read that Sherwin-Williams might actually make a really good stripper that attacks polyurethane effectively. The paint stripper that you find in Home Depot and Lowes is really targetted at furniture refinishers and applications like metal house trim items.

If you are removing the paint from an entire airplane, be aware of the environmental concerns. I understand that there are now paint removers that are environmentally friendly, but I do not have experience with them. What you do not want is to have your hangar designated a sire requiring formal environmental cleanup. Actually the strippers found in retail stores are not ideal for large projects like this.

PPG has a product called Eldorado PR , and there are many others, but I can't find anyone who will sell them to an individual - so far. I have stripped several vehicles with retail products and they are too much work. Originally Posted by PurpleZL1. Purple, I think someone gave you some bad info. Your checklist is filled with instructions for a disaster. Below is a list of things I see that are disasters looking for a place to happen.

If you cover your shop floor with plastic sheet, the stripper will drip down onto it and make a huge mess when it melts the plastic. Just use aluminum foil. If you cover the stripper with plastic drop cloths, it will melt the plastic into a gooey mess. A broom will not scrub the softened paint off. Use a plastic bondo spreader, or a small piece of aluminum sheet. You CAN use a steel wide blade putty knife. At one point you mention what Dupont recommends for priming.

Later you mention Sherwin Williams. What works for one brand may not work for another. If you have hail dents, fill them with body filler and after sanding it smooth, THEN put sandable primer over it. Don't but body filler on top of primer. You mention that the color stripes are added when the paint has cured for a certain time. After that paint is dry, you mask it off and shoot the rest of the plane.

Then when you remove the masking over the stripe color and there is your stripe. You also mention removing tapes as soon as possible while the paint is still soft. This will lead to a very ragged edge.

It is best to let the paint dry thoroughly before removing the tape. About 24 hours is usually a good time. Spend the money for 3M "Fine Line" tape. Before you spend many hundreds of dollars on stripper and make a big mess, get some or grit "wet or dry" sand paper. Fill a bucket with water and see how quickly you can water sand a one foot square down to the aluminum.

Don't sand over rivets unless they are counter sunk. Notice how long it takes you to do a one foot square. Then use stripper to do a one foot square.

Include in the time for the stripper the amount of time you spend cleaning the shop floor and power washing the stripper out of the seams on your plane.

Make sure you keep the hangar well ventilated when using the stripper. Thanks Pearson - I think the plastic drops cloth will depend on which stripper you use? Good point - I will update the list to check compatibility. Bondo over bare aluminum? I painted a few trucks when I was a kid and it was not unusual to find corrosion under old bondo on the aluminum cabs. It looks like commercial shop practice is to not sand aluminum skin and since it's pretty thin to start with that may be why. Stripe painting before or after is probably a personal call.

If you paint them first, you must deal with dust over the greater part of the plane while the stripes dry. Page 1 of 3 1 2 3 Last Jump to page:. All times are GMT The time now is PM. All rights reserved. Copyright EAA.

This does not contain methylene chloride, which is a highly toxic agent commonly found in paint strippers. Many aircraft paint shops will hire folks with automotive paint experience, that should tell you some thing. Saw a cherokee that got that treatment in navy blue. Solvent strippers Solvent strippers work on removing paint by either softening or dissolving the bond existing between the substrate and the paint film. Cover your skin, wear respirators that will shield you from solvent fumes, wear safety glasses, and gloves. My friend said this is possible and costs thousands less than the huge massive markup that aircraft paint shops charge.

Refinishing Aircraft Paint

Laser paint stripping is finally emerging as a credible, economical, and "green" alternative. Paint and other coatings on aircraft serve many purposes, including corrosion protection, erosion resistance, camouflage, radar absorption, and corporate branding.

Regardless of their purpose, these coatings require replacement from time to time—sometimes frequently, but usually every 5—8 years. The current dominant method of depainting for both military and commercial aircraft is chemical removal, which brings with it a variety of undesirable characteristics.

The list of negatives concerning chemical depainting is long, including:. Additionally, the requirement that manual sanding be performed on sensitive wing areas brings with it another set of problems, including high frequency of operator repetitive injuries, operator exposure to hexavalent chrome, the potential for damage to aircraft wing surfaces, and the lack of qualified operators.

It is no surprise that alternatives to these depainting methods have been sought for many years. In the late s, a flurry of USAF-sponsored work was carried out in search of the right laser and the right deployment means to address this challenge.

Now, three decades and many, many millions of research dollars later, laser paint stripping is finally emerging as a credible solution to replace the hazardous, environmentally unfriendly, chemical, and mechanical paint stripping methods that dominate aircraft depainting today. And, surprisingly, the boldest new initiative in laser paint stripping is being spearheaded by private industry. To prevent thermal damage to the aircraft surface, the laser energy must be delivered rapidly and briefly, either by pulsing the laser beam or by sweeping a continuous laser beam across the painted surface.

In either case, the top layer of paint is heated and then vaporizes, followed by immediate combustion as it leaves the surface and encounters oxygen in the air. The heat of combustion in laser paint stripping can be many times higher than the laser energy deposited to the surface, and efficient removal of this heated effluent is essential for process efficiency and workplace safety. All paints do not absorb laser energy the same way, and all laser wavelengths are not absorbed the same way by paints.

This process can be very efficient. This ability of CO 2 laser paint stripping becomes additionally important if removal of primer is required—a function that is quite difficult for the shorter wavelength to accomplish. This metric along with actual laser power is extremely important in understanding productivity, thermal loading on the aircraft, and overall process cost.

There are several major elements in delivering a laser paint stripping beam to the work surface. The first requirement is that the beam be delivered from a ground location to a scanner, which is located at the end of a robot capable of reaching the heights of a full-scale aircraft. However, given that the majority of aircraft surfaces are colors other than gray, it is obvious that a color-independent process should be adopted.

This latter consideration presents an obvious dilemma since it has just been shown that fiber-delivered laser power is far less efficient on light colors. And, at least for now, the new Q -switched, fiber-delivered lasers are not nearly as powerful as commercially available CO 2 lasers, and cannot be delivered via long fibers. So, the On the other hand, successful delivery of a CO 2 laser beam along tens of meters of beam path requires that many functions be provided, including circular polarization, collimation for a long beam delivery, beam path cleanliness particulate and gaseous , and beam path alignment compensation for changes in CO 2 laser output pointing, robot platform distortion, and robot arm s distortion.

Fortunately, a proprietary automatic beam alignment system has been developed to enable delivery of up to 30kW of laser power through the 12 mirrors necessary to reach the next beam delivery element—the polygon scanner FIGURE 3. This major element in delivering the beam to the work surface was developed by EWI as a response to the limited capabilities of competing galvo scanners. The polygon scanner has only one moving part—the polygon itself.

The stationary mirrors are water-cooled, and the polygon is gas-cooled. The scanner system is equipped with a patented process vision system, which monitors the color and location of the approaching surface to be stripped as well as that of the as-stripped surface. Finally, an effluent removal system is provided to improve stripping efficiency, facilitate vision, and prevent contaminant release to the surrounding environment.

Laser paint stripping is the only depainting process that reduces the volume of hazardous waste. Despite the feeling we may have inside one, commercial aircraft are actually quite large. The length of an Airbus is 73m, its tail is Manipulating the scanner and its paint stripping process around an object this size requires a mobile robot with eight degrees of freedom from any particular fixed location, and another two degrees of freedom to reposition the robot from location to location, around the aircraft and within the hangar.

The mobile paint stripping robot is equipped with many sensors, hardware, and software systems to provide operational and safety functions, including but certainly not limited to :. The software challenges presented by these safety considerations, in addition to control of the robot motion, laser, scanner, and beam alignment systems, are daunting.

Fortunately, the development team's primary systems design organization, Southwest Research Institute, has extensive previous experience in the design and implementation of large-scale robotics for media blast aircraft depainting.

The overall project development, design, building, financing, marketing, and management of this laser paint stripping effort represent a substantial technical and business challenge, and could not have been attempted by a single entity.

Instead, a global collection of corporate and government organizations has been assembled to accomplish the goal of laser paint stripping for large-scale aircraft [2]:.

Laser paint stripping offers a cost-effective alternative to the hazardous, environmentally unfriendly, current practices for military and commercial aircraft depainting. The laser power and scale of the mobile laser paint stripping robot described here dwarf all previous efforts in terms of productivity and sizes of aircraft capable of being stripped.

Other potential non-aircraft areas of applications include aerospace, transportation, marine, and public infrastructure. Business cases for potential laser applications depend on maximum process efficiency and deliverable laser power. It takes a multi-talented, committed project team to undertake an effort of this scale and complexity. See www.

Process alleviates costs and environmental impact STAN REAM Paint and other coatings on aircraft serve many purposes, including corrosion protection, erosion resistance, camouflage, radar absorption, and corporate branding.

The list of negatives concerning chemical depainting is long, including: The requirement to mask sensitive areas of the fuselage prior to chemical application; The requirement for personal protective equipment to handle the chemicals; Large water usage to rinse chemicals from aircraft; Large multiplication of hazardous waste volume; Release of carcinogenic hexavalent chrome primer into the waste stream; Personnel exposure to hazardous chemicals; The inability to use on aircraft wings because of chemical ingress; The requirement to de-mask prior to painting; and The cost of hazardous waste disposal.
