use a few cans of spray primer on it before you finish it. It'll seal it so you can't smell it anymore.Its been over a week since it was built, all the sealing should be dry.
Try what i said, and also try leaving it in the garage.
Ive heard of them smelling, but not so bad that your about to die.
And I bet it would dry faster in the van. Its like a greenhouse in there - humidity.
