Since OC2.0 has been off the market for years now, I assume this is an old application you are referring to? If so, the high spots are likely to be quite hard by now and I would personally suggest using an abrasive polish or compound to remove them.
Essence Plus is a non-abrasive "glaze" type of product meant to be used on top of a coating to help fill in light swirl marks/superficial defects while boosting protection. A high spot is the opposite of a scratch in that it is excess material on top of the surface, not missing material, therefore there is nothing to fill in or hide. I believe your only chance would be to use Essence Plus with an abrasive pad in an attempt to do some minor correction.
