If it's five minutes. I've doen drying with air before and it took 24 hours, and I think most peole would do it this way. But tests that they've done for oils (search for peroxidation and biodiesel, I think one of these comes up) shows major changes within a few hours of bubbling, which means that my drying I did last winter probably also had this effect (polymerisatin?) (what happens to oils and what happens to biodiesel is considered failrly similar I believe) mark
