When it comes to paint product shelf life, the hardener (if it does not have accelerators) normally a shelf life of 2 years.
The color (Aerothane) this usually has a shelf life of 4 years.
These times are usually based at storage of unopened cans and at room temperature or 70 degrees F.
If the cans have been opened and or the temperature has increased to 90 degrees F, you can expect the product to have lost some of it's desired qualities.
These would be poor application, orange peel or seedy, poor drying, little or no curing of the top coat, poor gloss, poor resistance to UV (fading or micro cracks) to name a couple of potential problems.
I don't know what the exact shelf life is of the Polyfiber products are, but they should be close to what I described.
If the cans have been opened and it was not you that opened them and stored them. I would take them to someplace that will accept them as waste.
Agreeing with others, structural adhesive, your life is on the line. The paint products, you really don't want things messing up after all the hard work.
Be careful guys. If you are intending to buy a partial completed project and he says he has lots of the original paint products that came with the kit (many years ago) First consider if you can and want to use it. If it ends up that you do not use it it is difficult to get rid of.
