I have some 2 year old left over epoxy primer. Should I scrap it and buy new or can it be used?

Barry, I know the activator gets darker with age, does that mean it is no longer good? I confess to using it that way and so far no problems.
Not related at all darkens does not affect.
If stored in a stable temp, I've used it at four years old and opened can.
We use to say the activator was suitable for three years opened, then had one stored in a plane hanger with no heat go bad in 2 years.
We said suitable for two years than we had one stored in a shed all winter and we went to 1 year.

What about unopened? I have some stored in one of my garages that isn't heated but well insulated. So there is some temperature swings but should never get below freezing. Also clear, 2k sealer, hardeners, reducer, etc? All unopened.

Oh I totally agree. Usually I keep chemicals in my home garage. Forgot about that box. Next year that garage will also be climate controlled. Just curious about all those products. Unopened as stated. I suppose I could use it up on used car work or auction cars.

Also, can solvent basecoat actually freeze? I've heard mixed opinions. Some say solvent basecoat is fine...freezing temps only damage water base.
It has nothing to do with freezing one or two days but freezing and warming over and over.
Can a one-time freeze destroy? Sure, but rare, its ordinarily long term and over and over
It is a wide swing in temps per day over and over that can cause problems long term.
be it 25 to 50, 40 to 70 like here today
Etc.
If unopened because, we purge the cans, good chance it is okay.
Water base like you said, one freeze and done.

Ok gotcha, yeah I know with hardeners I heard that was a big deal. I think some guys use bloxygen? To keep them fresh. But actual solvent basecoat that's been opened before...and not necessarily spi...say dbc can it actually freeze and be junk? I left a couple quarts in my car for a few days that I forgot about. It was very cold overnights. Seems ok to look at it?
When a base goes bad, it's called pigment kick out; it does not happen often, but when it does, you cannot strain kick pigment out, and it will spray fine but spray dirty.
Great thread, I moved in the middle of my restoration, life issues, had to reset up the garage, it's now been 5 years....
Have a lot of SPI Expoxy in cans, some not opened, question, are they still usable?
Anyone hazard a guess on the Single Stage PPG Urethane (Concept DCC)? Between the interior red (Deltron)and the exterior white, I have about $1000 tied up in that, the interrior red was $270 a pint if I remember right.
New garage is under the house, when I first moved in, I didn't realize it went below 32 degrees. Paint was in there for a few days in the cold before I moved it to the basement, which stays between 60 and 65 all year around.

Two days you're fine. We have shipped 100s of thousands of cans to western Canada and times on truck for 8 to 9 days in sub-zero temp.
I never had a problem.
One time to east Canada with temps in 20s in a case of the black base, it had pigment kick out, I told jobber whole case of gallons will be bad, but rest were fine. You never know.
