When working SwirlX be sure to use a small product on the test area and work it with light pressure, once you feel the hard paint dead on between your finger tips or with your hand and the paint then you are already pressing too. Work SwirlX for a good 2 minutes and remove it with a MF towel to see if the correction done was already sufficient and if you are satisfied with the results. If the correction was done, then just duplicate this on the entire car. If the correction wasn't done, then re-apply the product again with light pressure, if its still there, re-apply it again this time with moderate pressure, but take note its always better to do multiple light passes as compared to few heavy passes, this way you only remove a minimal amount of clear coat from your paint, and by doing multiple passes you would remove just the right amount of clear coat that needs to be removed.
