Probably the primer surface was contaminated before the topcoat was put on. Another option is that the paint was applied in hot weather, over a surface that was not cool enough to paint over. Still another option is that it was applied with a foam roller using too much pressure. That could have introduced air into the surface.
The fix is to sand the surface smooth, clean, then reapply the paint according to the manufacturer's instructions.
You have a contradiction ! - Latex primer CAN NOT BE oil based.
Oil based primer is the best bridge between oil and latex paints. If oil based paints are not available in your area, a high adhesion acrylic primer over a well prepared surface will also work.
You can use either a water or oil-based paint over a latex primer.
Not directly. You will need to use a primer made to adhere to oil and will accept a latex topcoat.
Yes. Oil based primer works over just about any surface.
