I just did an experiment stripping paint off a model. I tried 3 types of stripper before I was able to get all the paint removed. I first used PineSol then I tried Purple Power (Purple Pond) and last I used brake fluid. The first 2 I used were ok and do no damage. The model soaked for days and not an issue. Except the paint didn't remove completely. Then I used brake fluid. I checked it out just 4 hours of soaking and the paint just fell off. I wouldn't soak the model in brake fluid over night as it would end up a pile of plastic in the end. I made a video of it but didn't get it posted yet. I need to edit the video before posting. I will share the video as soon as I post it.
I've also used other things and I'll say you need to be careful. I soaked a model in alcohol and it turned the model into a plastic pile of goooo.
