Yes, all types of paint go bad eventually. A previously opened can of paint lasts 5 years on average if properly sealed and stored. Old paint shelf life can also vary among different types of paint.
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.
Open cans of paint don't last as long, but if the can is sealed after painting and stored in a cool, dry location, such as a heated garage or a basement, the paint can last for years. On average, paint lasts about ten years before it needs to be tossed, although some paint products may last up to fifteen years.
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.
It's recommended that you replace mascara every three months, lipsticks every year and eyeliner every three to six months (though pencils last longer than liquids). Primers and foundations usually last about two years, Zeichner said, and powdered products like blush and eye shadow are typically the same.

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. Once the primer is completely dry, it's prime time for painting.
Shelf life under normal conditions is two years unopened. Partially used cans might develop skinning if not tightly sealed.
In most cases, an opened can of paint lasts between two and five years. If stored carefully, it may last even longer. However, the storage environment, temperature changes and other factors can impact the shelf life.
Oil based paints have a shelf life of anywhere from 2 to 15 years. Depending how well it was sealed and stored.

Paint should be stored out of reach of children and away from food and drink. Most types of leftover latex paint, including AURA®, REGAL® and ben®, should be stored either in a lined metal can to prevent rust, or a glass or plastic container.
