The paints and primer can store almost indefinitely as long as they don't
freeze.  Once you open hardener it starts to absorb moisture and that is the
problem.  As long as you don't leave the cap off the hardener and store it
in a cool place without temperature changes it can last months.  You can
usually look at the hardener and see if it is good.  If it is still clear it
should be good.  If it gets cloudy that's when it takes on moisture and will
not work.

I'll let you know later, but I've had a can of hardener in the back of the
refrigerator for about 4 months.  It'll be a couple of more before I use it.
If I use it; it depends on what the other list members have had for
experience.

These are great questions. The one thing I have seen is that the hardener
doesn't have a really long shelf life after it's been opened.  Depending on
how you store it (cool storage areas are better), it seems that it can
degrade in as little as a month after opening.  It still works, but the
gloss seems a bit diminished and the surface hardness takes longer to
develop.  That's what I've seen at least.  It would be interesting to see if
anyone has found a way to make it last longer, for example would real cold
storage work?

What is the shelf life of PPG primer,  paint ,and hardener?

 

Once mixed, how long do you have to spray it before the paint quality is
degraded?

 

After the can is opened, what is the shelf life assuming the cap or cover is
securely attached?
