Am I correct?
thanks in advance,
I really don't see a problem applying oil based paint over a latex paint on a painting.
People apply oil based paints over latex primers all the time.
It's true that if this were a working surface, putting oil over latex isn't a good idea because that's putting a hard film over a soft one, and the result is that the hard film will be more inclined to "chip" off if it gets hit or impacted by something hard.
But, a painting isn't a working surface. You're not going to be storing pots and pans or stacks of dishes on it, you won't be walking or doing things on the surface of the painting.
In my view, what this artist has done is no different than putting oil based paint over a latex primer, and that's common. I'd only be concerned if this were a working surface.
