I got acetone. I got alcohol. I got mineral spirits. Heck, I've got gasoline out in the garage. I got enough volatiles to stay high for month and ruin my liver in the process. But I use 'em outdoors.

The rooms I doing have a patio door at the end of the large one; the smaller one has a window which is supposed to open but which I've never tried. The larger room also has a very openable window about 5 feet long and 3 high. There's also a door in the kitchen that leads outdoors and a kitchen window about 2 x 3 feet. I don't think ventilation will be a problem.
