After a successful first try on removing swirls from my Chevy S10 with my new PC I decided to attempt removing cleaning scratches and bug scratches from the Xpel installed on my corvette. I used a LC four inch spot pad(white) and used #2 Novas . This combo gave me great results but did not remove squeegie marks left by the installer. Evidently, the squeegie marks are all the way through the 3m Scotchcal. Otherwise I am pleased with the results.
