My point is that it may not be just drying, in the sense of some
solvent evaporating. It may actually cure to a different chemical
structure over some period of time, after the solvent evaporates.
Lots of paints do this sort of thing. Let it sit in the sunshine for
a few days. It might react with UV, too.
