I added GF extender and it worked great (I'm waiting for Target's version to arrive). I still have a few mistakes (in this commercial setting, no one is going to see these), but those seem user based errors.

I do heat my shop and my fluid. I used a cheap single burner, cheap cooking pot filled w/ water and got the product up to 68 - 70 F before spraying. I made sure my doors were 65 F or higher.

I had a brain fart and didn't take into account humidity. Since 1) I live in an almost desert and 2) I was using an electric heater / blower to help heat my shop up, my relative humidity was at 20% to 30%. The extender definitely helped.

I still get a few spikes (tiny fish eyes?) here and there... not quite up to my expectations for high end residential or a pickier commercial setting, but for the project I was working on it worked out great. I do think this product sprays better vertically or maybe I just need to practice my horizontal spraying.
