If the paint feels tacky when you are wiping it down, you didn't wait long enough. You can knock the high spots down with the applicator, wait 60 seconds and then wipe with a towel and you'll be good.
The new version (Gloss-Coat) seems to set up more quickly, although very forgiving with high spots if you catch them within a few minutes.
What I generally do is apply it to two sections of the car, then go back to the first one to find any high spots and wipe down. Then I apply it to a third section, then go back over the 2nd section for the wipe down. Basically apply to a new panel, go back to the previous one to remove high spots.
