A paint depth gauge measures the thickness of the paint on the metal panel and is used before, during, and after the polishing process. The indicator monitors how much paint is removed. It’s crucial not to go too deep and remove too much paint, which would leave it too thin and cause irreversible damage such as a strike through to the metal. Particular halogen or LED lights which replicate direct sunlight on the surface of the paint are used during this process to monitor the condition of the paintwork and validate how successfully the surface scratches and imperfections are being removed.
Some scratches or imperfections may be too deep or severe to remove without the risk of removing surface paint safely. In this case, a technique with the machine polisher and a special polish compound that rounds off the edges of the scratches and makes them less visible in appearance indirect sunlight has to be used.
After correction, the panels are wiped down with isopropyl alcohol which removes any oils that may have been left over from the polish process. Isopropyl alcohol reveals a true finish, highlighting any areas that may have been missed or require further polishing. Upon completion of this process, the paintwork will shine brilliantly and produce stunning shiny reflections because there are no longer any imperfections on the exterior paint.
