I use DOT3 brake fluid. Find it at your local auto parts store. It is inexpensive. I have found that soaking a part works best. I have never had any project take "days" to remove the paint. Paints are very different. Some will actually fall off, some take a little scrubbing and some need to soak overnight. I have tried every thing anyone on here has ever mentioned but "Wash Away" (but I will give it a try the next time I need to strip paint) and I have found nothing works better or more easily than brake fluid. Say what you want, it has worked for me for 40+ years!
I would stay away from commercial paint removers! I have seen them melt plastic. Swim At Your Own Risk!
I will say this, if you have made the grave mistake of painting a plastic model with lacquer paint, you are on your own and you deserve the mess you have created! If you use a laquer based paint to paint plastic, you need to FIRST spray the piece with a sealer so the laquer will not attack the plastic.
