Primer is formulated to bond well with the surface underneath, whether it's drywall, wood, or something else. However, paint sticks best to a primed surface rather than directly to the primer. If you leave primer unpainted and then decide to paint over it later, there's a greater chance of adhesion problems or peeling.
Primer isn't formulated for wear so if you don't apply a finish paint it won't look good long term. Dirt and grime may not wash off. I hate to suggest it but if you are only going to apply 1 coat you would be better off using a finish paint.
Your primed door may arrive looking pretty finished, but it will still need to be painted. The primer will provide a smooth surface, covering the permeable surface of the wood. However, the paint is required to provide extra necessary coverage against wear & tear, temperature changes, water splashed and more.
HOW LONG DOES IT TAKE FOR PRIMER TO DRY? Most latex primers dry to the touch in 30 minutes to one hour. But for best results, don't paint until the primer completely dries—which can take up to 3 hours, depending on temperature and humidity.
Sealed primer that has been properly stored (meaning it's kept in a cool, dry place, away from direct sunlight), can last for 2-3 years. It hasn't been exposed to air or bacteria, which are the main culprits in breaking down cosmetic products.
While the average shelf life may be estimated to be anywhere between two to ten years, it is important to inspect your primer and test it before using it on any other projects.
How Long Can You Leave Primer Unpainted? Most primers can last around 30 days exposed before needing to be re-primed. But remember – not all primers are the same. Some might only be good for 7 – 14 days.
Oil-Based Primer:

PVC cements, primers, and cleaners generally have a shelf life of three years, as do ABS cements and cleaners. However, CPVC cements have a shorter shelf life of two years.
Both canvas and wood will absorb paint if they have not been properly prepared beforehand, leaving dull colors as a result. A primer will fill all the small gaps present in the surface. It will fill in small and larger gaps as well as cracks and help to smooth out the surface.
So, no, you don't want to sleep in a freshly painted room unless you've used low-or-zero-VOC paint products. It takes time for VOC paint fumes to dissipate.
While pre-primed wood may seem ready for paint, adding another coat of primer ensures a better, longer-lasting finish. Primer helps paint stick to surfaces. The primer already on pre-primed wood is often applied in a factory and may not always be thick or even enough.
As long as the primer applies uniformly over the previous color, then one or two coats should be sufficient. Again, it is not necessary to apply several coats of primer to try to get a perfect white finish. That is the job of the topcoat (paint) which has to be applied on top of the primer.
It isn't necessary to use a Primer before foundation, yet there are many benefits to adding this product into your makeup bag. It all depends on your skin-type, skin concerns and the skin-finish that you desire.

Generally speaking, you should leave around two to three hours between coats of primer, but always check the primer can's instructions to be sure. It is a good idea to not use any more than three coats of primer when painting to avoid a thick undercoat that doesn't dry properly, leading to cracking or chipping.
A face primer goes underneath your makeup to help your makeup apply smoothly, stay in place and give your complexion an even-looking skin tone. Some primers also provide a glow-boost and extra skin benefits like hydration and moisturization, too.
The size of the primer is very important as well. Short primers are mainly used for amplifying a small, simple fragment of DNA. On the other hand, a long primer is used to amplify a eukaryotic genomic DNA sample. However, a primer should not be too long (> 30-mer primers) or too short.
It creates a sturdy foundation for your paint, anchoring it for maximum performance. So yes, the short answer is that primer is almost always a part of the exterior house painting process, but you don't always need a “full prime.” Sometimes all you need is a “spot prime,” covering just specific areas.

Unopened cans of primer can last up to 3-5 years, while opened cans may last around two years if stored properly. Store primers in a cool, dry place with the lid tightly sealed. Spoiled primers will show similar signs to spoiled paint, such as a foul odor, separation of components, or a chunky consistency.
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.
If you want to use it just to save some money it's doable, for example, I use cheap paint as primer, but with a twist, I thin it with alcohol so it dries faster and mix it with some primer (Vallejo).
