What kind of wire wheel would work best to clean the "ALUMINUM" seams and rivet heads - without damaging the Aluminum?

I plan to clean all the seams and rivets, so I'm happy with the results.
I'll let the painter sand the main part of the box, before priming everything.

Soda blasting. Link to Soda Blaster.

We have mobil soda blasters around here. I wouldn't try it, but they claim you can strip the paint from a car without taking the windows out.

Thinner brass wires will do much less damage to rivets, but will take longer to do the job. Soda blasting outdoors worked fine cleaning aluminum engine parts, but takes some time to get paint off. More mess but easier to work.

Either way, your health won't stand for the process until you are 100% or you have a full face mask and O2 bottle.

If you do it it may cost you more to have the professional painter repair the damage that you cause.

Let the painter do the job the way he wants it done. Any good painter will stand behind his work. If he wont, find a different painter.

Buy actual aircraft stripper and you won't have to do the rivets or spend much time on it at all. What is in your auto parts story says it's aircraft stripper but it's not.

The paint will be hard to get off aluminum with soda blasting. And soda leaves a film that has to be washed off properly or your paint will flake back off.

Not every painter has worked with ALUMINUM...

I thought it might be best that I thoroughly clean the crud from the seams and some of the rivet heads that have corroded.

I was not planning to strip the paint off the aluminum!

I was leaving the rest of the prep work up to the painter.

Al, I heard that since Feds banned Methylene Chloride these type of strippers aren't very effective. I have a gallon of the old stuff I'm saving to do9 my car in the Fall. What is your experience with new formulations? Phil

Not a painter, so no experience. The stuff I buy at Lowes works, if you give it time. Not a job you rush anyways.

I just stripped my car with stripper bought at Menards. “Two Minute Remover-Advanced” made by Sunnyside. Also tried some "Strypeeze" from local hardware store. Both are Methylene Chloride free. Very disappointed with the results. I had both doors on sawhorses to keep the surfaces horizontal. Slathered it on as thick as I could. It’s nothing like the stuff I used 40 years ago working in body shop doing strip and repaints. I tried covering the stripper with plastic after applying and letting it set overnight, but it didn’t help much. Some areas it took the color coat off, but left the primer, in other areas it just softened the color coat. Finished up with 80 grit on a DA to get to bare steel. Maybe other brands work better.

Many heavy trucks have aluminum cabs so I would take it to a shop that specializes in heavy truck work as they will know how to do it.

Most people DON'T know how to use aircraft stripper!!

You are to BRUSH it on ONCE in ONE DIRECTION and LEAVE it ALONE!

NEVER work it back and forth, like painting a house, to put it on!!!!!!!!!!!

I would check with the shop on what they want. I have experience with aluminum and the challenges with it. If it's corroded bad enough it's already under the rivets and will come back out anyway. Your only hope is a good primer/sealer.

It sounds like you don't plan on stripping the paint off which is good. No need to since it has special primers for adhesion to the aluminum. The shop will most likely block down what's on it and paint over it.

With the plane I stripped, I used real aircraft stripper bought from a supplier that supplies airports. It was not cheap, but worked awesome. I then blasted with corn cob to get the few areas that remained. Owner was very happy.

Current strippers in the US anyway is meek. It is very mediocre. Nothing like the older formulations/

More of a reason to do as the instructions say.
Brush it on in one direction and leave it be.

It has something to do with how the molecules work or react and not to mess with them once it is applied..

Yup. Even with a good primer/sealer, aluminum expands and contracts and that seal will eventually deteriorate. Once corrosion has set it, it will come back. And the first thing people do is blame the painter/body guy. It is impossible to see what is going on under every rivet and at every seem.

One quick trip to a local airport with private aircraft can get you the information you will need for stripping paint off aluminum along with the proper primer-sealer.
Pilots have their favorite products and painters, just like car guy's.

We went through this with my Brothers Cessna 170.
