So most often, if you’re going to paint over existing paint, we suggest sanding it down with relatively coarse paper (180 to 220 grit), and then either shooting the whole body (preferably), or just any rough, dinged, or bodyworked areas, with a good, catalyzed, high-fill primer.
Likewise, can you repaint on top of clear coat?

One may also ask, do you have to prime car before painting? Primer is paint only because it goes on the car and does have some tone of color. Their purposes are vastly different, but in many cases, one can’t survive without the other. You want your paint to be strong and adhere well to the surface below it, so you should always apply a coat of primer before you paint, correct?

Can I put primer on top of paint?
Priming is best. If you have to do two coats of paint to cover the old color, why not use a good primer or primer/sealer and one coat of a good paint? Most people will say otherwise, but primer will stick to old paint a lot better than new paint will. Use one coat of primer and one coat of paint.
