Drying cabinet help/questions, please.

Hi, I have a guitar that is getting ready for finish. I usually finish outside and let the guitar hang in my shed until cured, but it is getting on toward winter and the low temps will not allow this. I was thinking of building a sort of drying cabinet out of plywood and caulking all seams so it was airtight, with a rubber seal on the door, in the hopes that I could spray outside during the warmer daytime hours and seal it up in the box to bring inside. Has anyone done anything like this? Will this contain the fumes, or will the plywood be pourous enough for them to gas out into the house? Or will the off gassing inside the box eat away at the caulking, build up pressure inside the box, or be dangerous in some way(explosion, combustion, etc.)? Or will containing the guitar and gasses the finish gives off in an airtight container interfere in some way with the curing of the finish? I'm using aerosol spray lacquers. Any help/thoughts appreciated.

The lacquer needs air circulation to cure properly. Some people use fans to speed up the curing. I spray in my garage which is pretty cool in the winter. What I do is make sure the lacquer and body is warm, room temp anyway, use a stick screwed to the neck pocket as a hanger. After I spray it I bring it inside and hang in the spare bathroom. I have a small heater in there to speed things up and a towel along the bottom of the door takes care of the fumes, if it gets too bad I just crack the window for a few minutes.

i have a tall narrow cupboard set up with a 100watt flood light in the bottom with a perforated shelf above it - the bodies and necks hang above it - works pretty good

Thanks to all for your help. I think I'm gonna go with a box and lightbulb vented to the outside of the shed. However, is it realistic to worry about the heat from the bulb igniting the fumes, or the possibility of a spark from the lamp doing the same?
