I thought I would add to this because I have recently been working on stripping some paint (three layers) and have tried multiple products and techniques. Keep in mind that I have not been supremely successful at this every time, and that I have spent countless hours of time using a power washer because of the less effective methods I have tried. Below is the technique that has worked for me, and I finally achieved the "paint is all gone to the bare metal with no effort" nirvana that I thought was impossible. But even that was on a limited basis.
Supplies: 5 gallons of Bonderite S-ST 6776 LO Aero (it is also called Turco 6776 LO) $125 from Avial other people and they can deliver it to your house. This stuff if not the peroxide based super tree friendly stuff, but it also should not impact your ability to reproduce as much as the "aircraft stripper" stuff found in stores. It smells terrible. Did you ever read the label of the "aircraft stripper" stuff from the store? It says "not for use on aircraft."
Harbor Freight 1.5 gallon texture sprayer, probably start with the smallest nozzle. $22
Take a look at how many plastic paint drop cloths you think you need, and then buy 4 x more than that
Access to an air compressor (for the texture sprayer)
Power washer
Full face respirator- this will help keep overspray out of your eyes and the smell out of your brain.. You do like to see don't you? I have the 3M version and it is about $140 on amazon
Rubber gloves
Aluminum tape
coveralls, tyvek suit, or whatever it takes to not get stripper on you. The stripper, not the glitter is what you are worried about.
Warm weather
Forgiving neighbors
How to:
Block of your windows, holes, and anywhere else you don't want stripper to get on your airplane. The more disassembled your project is, the better
Lay down a layer of plastic and place all of the parts you removed on top of it. On the ground is way better than a sawhorse. Trust me.
Hook up your fancy paint spackle sprayer and fill it up. Spray stripper until your heart is happy.
Once you have sprayed the individual parts that are on the ground, turn them upside and then cover them up with another tarp. This should just be a loose tent not a saran wrap vacuum packed affair.
For the rest of the airplane, spray it and warp it up in plastic. I tried the packing saran wrap stuff and it was too tight. Tent the thing and let it cook overnight. It will most likely take another application on the vertical surfaces. I like to use a plastic scraper and get the loose paint off, then reapply and let sit another night.
Once the warm 24 hours has expired, unwrap and throw all of the plastic in the garbage after you use the plastic scraper on the loose paint (this will prevent having one million pieces of old paint on the ground after you power wash).
Get your pressure washer out, preferably one with hot water and commence to washing. I like to follow up with a bunch of dawn dish wash soap, a scrub brush, and lots of water.
This whole process is still challenging, but the right products, application, and removal is the key.
Good luck
