A good primer.
No, you either need to really rough up the oil paint with fine sand paper, or put a base coat on before you paint with your Latex paint. If you don't your Latex paint won't adhere.
A good latex finish will almost always out-perform an oil based finish coat. Your needs will determine what is best and variables will include the intended use of the product.
The best base coat for painting walls is a simple primer, usually white that will cover the wall in a simple finish. A further coat may be needed afterwards.
The best method for preparing a surface for painting with latex paint using oil primer is to first clean the surface thoroughly to remove any dirt, grease, or debris. Next, sand the surface to create a rough texture for better adhesion. Apply a coat of oil-based primer and allow it to dry completely before applying the latex paint. This will ensure a smooth and durable finish.
You can always paint latex ( water based )over an oil based paint as the latex just dries on the surface. However don't paint an oil based over a latex paint. Oil based paints need to absorb into the wood or other surfaces or it will just dry and flake off.

yes Yes, an oil paint will adhere to latex. It doesn't work in reverse, latex will not adhere to oil that is dry, but oil adheres to dry latex. If you were a purist, though, you would sand down the woodwork before repainting it. That would give the best result.
When using oil-based primer with latex paint, it is important to follow these best practices: Ensure proper surface preparation by cleaning and sanding the area before applying primer. Use a high-quality oil-based primer that is compatible with latex paint. Allow the primer to fully dry before applying the latex paint. Stir the latex paint thoroughly before use to ensure proper consistency. Apply multiple thin coats of latex paint, allowing each coat to dry completely before applying the next. Clean up any spills or drips immediately with the appropriate solvent. Follow the manufacturer's instructions for both the primer and paint for best results.
You need to rough up the surface of the oil paint with sand paper or a light coat of stripper.
When you say rubber base paint I assume you mean latex paint. Yes, latex paint will adhere to an existing epoxy finish. However, the epoxy must already have cured. Meaning, it was already applied sometime in the past. A pretty good rule of thumb to go by when you're unsure if two finishes are compatible is to apply a coat of primer. Also, when latex paint is applied to a primed surface it will last that much longer, appear more uniform and will usually require only one coat of paint for proper coverage.
