Paint stripping: Globe Model Coach >>>> figurative Wall

Trying to turn an old Globe Models (Pre-Athearn) assembled PRR coach into a Globe Models (Pre-Athearn) assembled unpainted coach. Alcohol bath, 91%. Well, a few days solid now in an enclswed container, and it’s done very little. The lettering scrubs off, but the exterior paint is still stuck fast. Some of the lcohol did make it insode the body, and now a few of the windows are clouded, and most of them have an oarngy color to them.

Oh, and I can’t get it apart, with a concern for breaking it in the effort. It;s the obvious answer though. If you aren’t familiar with Globes, you plastic weld the windows to the walls to the ends to the floor to the roof. The bulder did a solid job. I’m thinking I need to move up to the ELO, but that doesn’t help the winders. So, taking he obvous into account, what do you guys think I need to do? Or is tat really the only approach?
