A simple rule of thumb is
that you can always put latex over oil, but not vice versa.

Not a reliable rule of thumb! In my experience, the only way latex will
stick well to oil, is if you thoroughly rough up the oil, then use a good,
preferably oil-based primer to assure adhesion of the latex over the prime
coat.

Sorry, that was over-simplified. Latex over oil PRIMER, but not the
other way around.
