Primer Gumming Paper

I know I should have went with SPI, but anyway... I sprayed two coats of Transtar 2K Quik Prime and it doesn't seem to want to harden. I sprayed 2 med-wet coats in my garage. Temp was about 60 degrees and raining outside. I let dry overnight, and when I try to sand it, it wants to gum up the paper. I'm using 3M Crystal Coast paper. 180 doesn't gum too bad, but 320 is terrible. Any ideas? The primer almost feels plasticky.

Until the primer cures it will continue to clog the paper. You need to investigate why it hasn't cured IMHO.

I'm sure I got mix ratios right. Could the temp been too cold and/or humidity too high? Do I just need to let it set till I get some warmer temp? Other than gumming paper, did this hurt anything?

Well if it fails to cure properly I would not do any work on top of it until it's all removed . Try placing it in the sun for a whole day and see if that helps.

You could also try putting some lights up close to it. I use my halogen lights to help filler and primer to "kick". Don't get them too close, however, I think you can actually overheat everything and cause other problems. I usually put mine 2-3 feet from the closest surface. Even if you can't get heat on the entire car, you can at least test to see if this sets up the primer in a specific area.

Id let it sit longer with lots of ventilation, open your garage/windows if you have to. Paint dries when solvents evaporate from it, having good ventilation does just that.

Evaporating of the solvents is only a small part of a 2k primer cureing.
I know you probably do not know this, but what was the surface temp of the part you were painting?
I have used Transstar primer surfacer, it seemed an OK product to me.
It might be too late, but I would try to put some heat on the part. Either direct sunlight, or heat lamps of some type.
I would also see if the paint comes off with a solvent, wear gloves.
If it does, you might need to strip the whole part, and start again, when it is warmer.
