I use a dehydrator routinely for all my painted parts, and it works wonderfully with all types of paints. It shortens the curing time by a factor of approsimately 8, which means enamels are fully (and I mean fully, no smell at all and very hard) in three days, acrylics in 2 hours, lacquers in 12 hours...). The bonus is that it protects the painted part from dust, even when running with the fan (I never had a speck of dust in any of the parts I put in).
