You didn't say whether the latex was flat or shiny, makes a difference.
You will however not gain any advantges to doing this as your fnish will
only be as strong as it's base or primer. Al
p.s. mark ransely is an idiot
It depends on whether the latex or the oil paint will end up on the
sweatier side. Latex lets moisture pass through it, but oil doesn't,
so if you paint the outside of house with latex, then you can't use
oil over it since moisture from the house will become trapped
underneath the oil. On the other hand, if your interior walls have
latex on them, you can probably put oil paint over them without
problem (sometimes used as a vapor barrier).
The paint can will tell you if you have to prime (doesn't anybody read
directions?), but you usually do.
I just had a terrible second thought based on your message. I put two coats
of oil porch and floor paint over one coat of that high-adhesion Zinsser
1-2-3 waterbased primer.
Sounds to me as if I may have done exactly what you say I shouldn't have
