Before polishing begins, a thorough inspection of the paint is performed using various lights and a paint depth gauge to assess the condition of the paint and look for defects. In my opinion, what makes a true professional detailer is someone who has the tools and knowledge to fully assess a vehicles paint, use that info to correct paint defects, and at the same time leave as much clear coat as possible. This paint depth gauge allows me to accurately assess the current condition and history of the paint. These readings will tell me if there are any areas where the clear coat is thin (due to heavy sanding/compounding or even sprayed at the factory) and to be very cautious working that area or avoid alltogether. It will also indicate if a spot or panel has been repaired/repainted which may react differently to the correction process used on the rest of the vehicle. So why am I even bothering using it on a brand new vehicle that the owner has never had detailed? Well, I believe you can never be too cautious and repairs DO happen to brand new vehicles at dealerships.
