My biggest problem is patience. I have none, especially when it comes to drying Time.
So I made up drying cabinet out of an old Armoire using old school light bulbs to heat it. 1 150 Watt bulb at the bottom of the Cab and 1 100 Watt bulb at the top. That puts the Temp in the Cab at about 120F of nice dry heat.
About an Hour after the Frame is sprayed it goes in the Cab to "Cook". The finish is usually nice and dry after about a Week. Or when you can't smell Paint anymore.
