if I understand correctly, the warm temp reducer results in less orange peel, correct? Is that because up takes longer to evaporate, giving the paint more time to "spread out". I was using the medium temp, but the high temp stuff may be worth a try. Thanks!

That is my experience as I tried to describe in an earlier portion of the thread.
That said, much of the orange peel is a result of less than perfect gun adjustment and technique. Finish paint wants a smaller tip than filler and more attention to adjustments. Big droplets coming out of the gun not fully atomized are not going to be as flat as finer mist.
It takes a long time to become a good painter and most of us get to be good sanders first.
For sand out look at 3m Trizact sanding discs used on an orbital sander. 1500 grit, followed by 3000 grit will make it easier to do a good job. Contact me privately if you want more detail.
