Used it didn't do real well with scratches made swirl marks on corolla. Make sure you don't use a rough terry cloth it'll ruin your paint job like a harsh rubbing compound. Seems more like a polish for clear coat then scratch remover. Use the correct rag when you buff it out too. One for polishing and another for buffing. That way you don't smudge the dirt all over and over.
I also did it another way dipped my finger with a soft rag wrapped around it in a cup of water. Applied small dab to my damp rag & buffed. Didn't crust up and was easier to get a gloss out of it.
