To answer your question about paint not fully cured, I have never seen a paint coming out of the dehydrator not gassed or dry. However I have had fingerprint problems with paint cured at ambient temp!
In short, it works! Just set the temp below 110F and nothing bad will ever happen.
I agree With Zoomzoom, this "tool" has now become invaluable to me, it saves me a lot of precious time. I do not have much space in my garage, but I refuse to put it away as I want to be able to use it anytime. That's how I like it.
