Going down the Paint Stripper wormhole

Hoping to find something local, but not finding anything with methylene chloride, which is commonly recommended on this platform.

The most common stripper locally available is Klean Strip Ultra, Ingredients:
109-99-9 60.0 -80.0 % Methanol {Methyl alcohol; Carbinol; Wood alcohol} 67-56-1 3.0 -7.0 % Ammonia {Anhydrous Ammonia; R-717} 7664-41-7 1.0 -5.0 % Xylene (mixed isomers) {Benzene, dimethyl-} 1330-20-7 1.0 -5.0 % Proprietary Ingredient 68439-46-3 0.1 -1.5 % Hydroxypropyl methyl cellulose 9004-65-3 0.1 -1.5 % Ethylbenzene {Ethylbenzol; Phenylethane} 100-41-4 0.1 -1.5 %

or

Rust Oleum Paint Stripper, Ingredients:
Methyl Acetate 79-20-9 25-50% GHS02-GHS07 H225-319-336 1,3-Dioxolane 646-06-0 25-50% GHS02 H225 Methylal 109-87-5 10-25% GHS02 H225 Solvent Naphtha, Light Aromatic 64742-95-6 2.5-10% GHS07-GHS08 H304-332 1,2,4-Trimethylbenzene 95-63-6 1.0-2.5% GHS02-GHS07GHS08 H226-304-315-319-332-335 Methanol 67-56-1 1.0-2.5% GHS02-GHS06GHS08 H225-331-370 Dimethylethanolamine 108-01-0 0.1-1.0% GHS02-GHS05GHS06 H226-302-312-314-331-335

I dont want to damage my aircraft, so open to recommendations. The paint on the aircraft is old and not sure what chemistry it is, it's definitely single stage paint.

I just sat thru an Evoke seminar at Sun n Fun and they went over their whole process. They are using Aero Clean LPH-400 these days. It’s peroxide based and doesn’t have the disposable issues of the hard core stuff.

I used this stuff, called DeBond, but not sure how widely available it is. I tried the methylene chloride stuff as everything else I could get my hands on, but nothing would really touch the epoxy primer on my plane except this DeBond stuff.

I slathered it on and let it sit for 24 hours (it was cold when I was doing it) and when I came back the paint, and primer, was literally falling off the airplane. Wish Id discovered it earlier.

No nasty fumes either.

I was in the coatings removal business for 34 years. To bad we can't get the Methylene chloride based stripers, they worked well. Most aircraft paint shops now use hydrogen peroxide based strippers and seem to have good results with those. I do not see anything that would be harmful to aluminum or steel in the 2 products you gave MSDS sheet ingredients to. They may remove your paint depending on its composition; some paints/brands have better solvent resistance than others . It could be that one of those strippers would work better than the other in your particular case.
 
So my two cents. the USN uses Vantage B&B™ 3095 at the facility in Jacksonville for removing aircraft paint. it seems to work well.

think you got the wrong part #. LPH400 is the part number for a Iwata spray gun.

I bought an unfinished Rv6 that the wings and fuel tanks were built in the late 80's, unfortunately the tanks were sloshed. I'm still building and want to remove the slosh before completing. I'm not a chemist and don't know the chemistry of this product but I'm assuming it is similar to paint. Does anyone here know if any or which chemical would work best for removing slosh coating?
 
A very good paint stripper is EFS-2500. It's manufactured locally here in The Vancouver, Canada area and we've now used it on 3 aircraft. It's not the fastest at stripping but very safe, put it on thick, wrap it in poly and come back days later for scraping fun times.

It has many approvals including Boeing and is used in the field for many large jets. It has more approvals than many of the common other "aircraft paint strippers".

Slosh is easily removed with Professional strength Goof Off. Within 10-20 seconds it peels the slosh
 
Interesting note about methylene chloride (dichloromethane) is that although it's not legal to sell as paint stripper, it's still used in a lot of products.

More interestingly, there's a product, Discovery "Carbon Off" that's a methylene chloride-based gel that looks and acts just like the old fashioned paint stripper. Except it's not intended for stripping paint. If you have annoying carbon buildup on your plane this is a great product but be warned... it's EXTREMELY hard on paint.

Why go half way? Anyone else remember a Steam Jenny? Watched the old-timers long ago get the last stubborn primer remnants off of old projects. Seemed to work when all else failed. Must be a down side as I don’t recall them even being mentioned the last couple of decades.
