Not amazingly if I am honest. In some larger surface areas it really did blister off the paint quite well so it came off with ease, but I think part of the difficulty was down to the colour changing paint. I have heard this tends to be thicker or something. In the end I had to rely rather heavily on the wire cup attachment to "brush off" the rest of the paint. This actually resulted in more abrasion on the aluminium than I had hoped for, but I should have probably foreseen this.
If I were doing it again I would probably try to find something to thicken the dichloromethane so it is like a gel (like nitro or something). Alternatively, for a few frames at once, creating a shallow bath dip and just giving them a soaking one after another could be a good approach (anyone want to organise a frame-stripping party? I still have about 4L left!).
Also note that gloves are ABSOLUTELY NECESSARY. I got some of this on my skin (through two pairs of latex gloves), and it was very irritated!

I looked into thickening agents, it was a rabbit hole of organic chemistry that I didn't full understand. People kept saying thinks like 'apparently paraffin wax will thicken it' and I had visions of my neighbours muttering 'apparently he gassed himself to death trying to thicken paint stripper' as the hearse drives off.

Exactly my experience with the stuff, absolutely deadly if you accidentally breath it in.
Did think of this, but haven't had a chance to test it. How well did it work?
