It may be easily polished off w/Essence. If not...I've had an occasional challenge where I did not apply it just right.
(I used Essence in the sun, the car panels were hot, too much Essence on the pad etc.) I use small pea sized drops.
Now that I have my Essence product/process figured out I get a lot less "gummy-bears" issues when I use it.
Essence is an awesome product but IMHO there is a small learning curve to using it. Do not use it like M205.
So in short...yes, I have had stubborn Essence residue. If you don't use it right you can get "Gummy-Bears"
The removal "trick", I have learned, is to wipe the paint with straight IPA and it easily stips off.
The downside is IMHO, IPA completely removes all the Essence (and all its magic) from the paint.
Essence should then be reapplied. This is where the tiny amount, gloss pad technique comes into play.
Essence is not your local auto parts store polish. (M205, Ultimate Polish) Essence is magic in a bottle.
It's easy to "learn" how to use Essence correctly but it's nice to know, if you "mess up", IPA can strip it.
NOTE: If you are using a coating be sure (from every direction) that you have NO "streaks" before applying the coating.
Learn Essence: Put it on, take it off and, put it on again using a Carpro Gloss Pad. Spend some time and learn it's properties.
In your case, Essence then just Reload, is fine. No foul. No harm. Side Note: A temperature gauge is a great little investment.
Remember: Essence has an very fine abrasive. Essence Plus does not have any abrasives.
You can put a coating on top of Essence. You can not put a coating on top of Essence Plus.
