I just watched the video and I did not take it as being able to correct a coating only.....
To me it looked like he was showing what he would do on a coated panel that has accumulated light to medium damage.
Just going the absolute bare minimum to remove the damage with a combination of Essence, Essence Plus & Angle wax polish with a no cut foam pad then doing a ipa and he re-coated the panel.
It really does not take much to remove a coating by machine.
If ya want to see just put a test spot on one of your windows but don't wipe it off, leave it as a high spot. I say window because coating high spots stick out like a sore thumb on glass, then see what it takes to remove it.
