[NSRCA-discussion] PPG Concept Paint Qs

[tbruzewski at aol.com]

 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?
