2K regular primer tech manual says mix only what you immediately need. What exactly does that mean? Mix only enough to fill the cup on the gun? Mix enough that you may spray in 30 minutes? Any guide lines for me?
I gotta ask if there is more to this story. Barry said gel time is 150 minutes and you got 15? Did you use polar?I sprayed some 2k SPI the other day for the first time in awhile, forgot i ordered it awhile back. Anyways, I'd say after 15min and going back to shoot a second coat it wouldn't spray. Lesson learned!
But on another note, it seemed to lay out smoother than I remembered.
Could of but lets say no polar and 70 degrees.I gotta ask if there is more to this story. Barry said gel time is 150 minutes and you got 15? Did you use polar?

#4 is a constant.I mixed up 20oz.. I just mixed it how I normally do. stir it up for a min then dump in my gun. I dont really over think these things! No polar was added.
Primer and hardener have 2018 dates on them.
I am by no means complaining here. I havent sprayed the 2k in a minute and have been using only epoxy so I was used to a very long window.
Here is my exact process if this helps.
1. Mix up primer (20oz)
2. Sprayed first coat, went on real nice.
3. Put the gun on the stand, hit up youtube and IG while I killed 15 min.
4. Sat there and pondered my life decisions and what put me in the position that I need to do this stuff every night after I already work all day.
5. Snapped out of it and went for to the second coat.
6. Went for a second coat and it sprayed really dry... ok here we go......Cleaned the gun, the primer looked liquid, stirred it up...went at it again, and it did the same thing.
7. Removed the dekup again and the primer was clogged up in the gun. so I just mixed up another batch and that was that.

Maybe I'm just blessed but I have never had any issues with the regular 2k primer. It's all I have ever used for a few years now.
I bet there's dried buildup in the tip. Try cleaning the tip between coats.@orangejuiced86
Been my experience as well. First coat sprays nice, second coat dryish. Both the Regular Build and Turbo. Why? I don't know maybe Barry could give some thoughts.
I've got a bunch of priming to do in the next day or so, I'm going to try some retarder even though temps inside will be around 65. See if that extends it a bit.
