do you need to sand before using Zinsser primer? This would depend on the surface you are painting along with the specific product. On the whole, we'd recommend sanding uneven surfaces or those with existing paint for a nice smooth finish; however, Zinsser Bullseye 1-2-3 will adhere nicely without sanding.
Sanding after applying primer will help you keep the surface as smooth and flat as possible, eliminating any leftover bumps, dents, brush marks, etc. And that sometimes happens if you didn't' check it well before priming. Consequently, it'll help you to achieve a bright final coat and that's not dull.
Dries to the touch in 20 minutes, can be recoated in 45 minutes. The primer film develops full adhesion and hardness after it cures in 1 to 3 days. Lower temperatures, higher humidity, and the addition of tint will prolong dry and cure time. Allow more time at cooler temperatures.
The drawback to using shellac-based primers is that they are not as versatile as latex or oil and they give off more fumes. They require that you use denatured alcohol to thin them and clean applicators.
You only need to sand if there are brush strokes or other blemishes. Also you don't need to sand between coats. I only sand if I have brush strokes or drips (I'm finally getting to the experience level where this rarely happens).

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.
When sanding, do a first pass with 100-150 grit sandpaper then finish with a second pass of 180-220 grit sandpaper. Remember, the higher the “grit" number, the smoother the finish.
Unlike regular sandpaper, it just removes gloss; it can't be used to smooth the surface, correct imperfections or as a paint primer. Liquid sandpaper is also referred to as deglosser and wet sanding. The advantage of using liquid sandpaper instead of regular sandpaper is that it's easier to apply and safer to use.
In most cases only one coat is necessary to prime most surfaces. If excessive absorption occurs over very porous substrates a second coat may be necessary. Spot priming is recommended only under high-hiding topcoat paints. For best results prime entire surface before painting.

Oil based primers are also good stain blockers but aren't as good on shiny or difficult surfaces as shellac based primers. Oil based primers are great for wood, metal and interior walls and act to prepare the surface for the next coating be that an undercoat or a topcoat of paint.
