moisture issues

[DC932]

I've read about how 2k primer can absorb moisture in the air, but can this be a problem if it can also be wet sanded? Once I spray 2k over the epoxy, is it ok if I don't get to sanding it for a few weeks? The car stays in the garage 24/7.

I have never seen any test to prove exposure to air was a problem, all I'm aware of is primer getting wet with cycles, like being driven in rain for long periods.
Wet sanding is done every day and as long as allowed enough time to dry, not an issue

i think where people get in trouble is they wet sand then as soon as the surface drys they shoot another coat trapping some moisture . i wet sand everything but i stretch the dry time .
