If it's vented properly, it gets to temperature and stays there. You have to measure the heat, and adjust the vents accordingly. You don't have to sit w/it. I leave cars in there for hours/days.
Someone told me that for every 10 degrees increase in ambient temperature, you will cut drying time in half. So if your dehydrator is 110 degrees and ambient air in your house is 70 degrees, what would take 8 hours to dry would take 1/2 hour at 110 degrees. Or if you used to wait a month, you can figure a couple days in the dehydrator. Based on my own use, I'd say the figures are reasonably accurate. In real world terms, you can get away w/spraying a body and be able to polish it in a matter of hours, or at least overnight. Flat acrylics dry almost immediately.
