I've used the product multiple times and have found near little to no value in it when it comes to hiding anything. It will bring back a certain level of slickness and hydrophobic property but overall meh. Coatings are microns thin and I've yet to see swirls in a coating that can be removed for more than a week by simply applying another product.
You probably used it wrong as I have repaired many coatings with it successfully. The product works as advertised.
