My brother has used a lot of PVC pipe in the high desert, where it's cold and hot.

Primer is good, it makes the adhesive grip better.

Both primer and adhesive (in original containers) can take the cold (freezing) but not heat. Heat makes some part of the contents evaporate, which makes the stuff useless.

Since it can be very difficult to reseal the cans, several smaller cans of primer and adhesive are better than one large one.

PVC isn't very tolerant of UV light, as mentioned above. The easiest way to protect without taking up valuable storage space is to bury it, marking the spot.
