Paint correction is a term that is now commonly used by both professional car detailers and car cleaning enthusiasts to describe the process of restoring the paintwork of a vehicle, mostly through the elimination of surface imperfections, that dull, oxidize, or haze the surface by reflecting light off in various directions, therefore detracting from a true and proper, clean, sharp, reflection of the paint. These imperfections include things like swirl marks & fine scratches, bird dropping etching & acid rain etching, hologramming & buffer trails, and random isolated deep scratches.
After correction, the panels are wiped down with an isopropyl alcohol which removes any oils that may have been left over from the polish and reveals the true finish, including any areas that may have been missed or require a little more work. Once complete, fully corrected paintwork will shine brilliantly and produce stunning reflections because there are now no longer any scratches and imperfections to scatter and reflect the light rays off in different directions.
In conclusion, paint correction is the process of removing surface scratches and imperfections from a vehicles paintwork, which involves the use of machine polishers and a range of different polish products. A fully corrected vehicle when viewed in direct sunlight will show only true reflections and no swirl marks, scratches or blemishes will be visible to the naked eye.
