Bonding primers are best because they are formulated to adhere to glossy surfaces, such as oil-based painted finishes. If you use a very high-quality bonding primer, you might be able to paint over oil-based paint without sanding, but always read the primer's instructions.
Shellac Primers - These primers can be used with both oil-based and latex paints and may be the best at blocking stains and can even seal in smells that may be coming from the surface you are painting. They are fast-drying and can adhere to almost any surface.
You can paint older oil-based paint without sanding, but it's not always the best idea. If the oil-based primer or paint is in good condition, you may be able to get away with just painting over it. However, if the paint is starting to chip or peel, you need to sand it down before painting over it.
Use on interior and exterior surfaces including woodwork, drywall, plaster, paneling, masonry, brick, painted metal and properly prepared glossy surfaces†. Use under or over water-based or oil-based paints. Not recommended on flooring.
It's simple and straight forward to prime old oil paint with a fresh coat of oil-based primer. Oils bond well to other oils and oil-based primer provides an excellent base for any paint. Once you prime with oil-based primer you can top coat with either oil paint or latex paint without issue.
In addition, water-based paint is preferred when covering an oil-based product because it has a faster drying time and resists fading in the sunlight for exterior applications.
Apply a bonding primer that is specifically designed to promote adhesion between oil-based and latex paints. A good quality primer I like to use is Stix. I also use this on my kitchen cabinets before painting them. Once it's dry do the scratch test.
The two types of paint are not compatible, and if you try to apply oil paint over a latex base, you can expect issues like cracking and peeling. So, it's best to avoid using oil-based paint over latex. On the other hand, you can use latex paint over oil-based primer, but proper preparation is essential.

Can you paint over primer without sanding the car? Technically, yes, you can do that. Some circumstances don't require sanding the existing paint and primer before repainting. If you choose this route, the car's surface might show minimal damage like puncture holes, body scratches, dents, and cracks.
Covering with water-based paint: You can't paint over oil-based paint with water-based paint directly, but you can after some crucial prep. Doing the correct prep: Always sand the glossy surface of oil-based paint before applying water-based paint. This step ensures better adhesion and a smooth finish.

Latex paints will not stick to oil based paints. The exception is that an oil based primer may accept any kind of top coat paint. For that reason, an oil based primer is recommended to be applied over any oil based top coat, then a water based paint may be used as a top coat.
Not all primers are created equal. To solve common painting problems, choose the best paint primer for the job. If your paint job entails indoors and outdoors, an interior/exterior primer is good to use. Otherwise, use separate primers formulated for indoors or outdoors.

Applying layers of paint
Start by adding areas of shadow and light, fill in large areas with color, then work patiently, laying on more and more intense layers of color. You need to follow the golden rule of oil painting: painting "thick on thin" .
