Paintwork Inspection: Car Detailing Tools from NexDiag & Meguiar’s

When imperfections on a car aren’t budging with your usual car care methods, taking your detailing expertise a little further, such as machine polishing, is often the next port of call. You may well already have the machine polisher, pads and compounds needed to get yourself started, but there are a couple of other important tools which should always be considered too for paintwork inspection.

The initial paintwork inspection or vehicle appraisal that is undertaken prior to beginning any form of machine polishing is always crucial. Understanding what surface imperfections there are to correct and also how much paint you have to work with will give you the best possible insight into approaching the task in hand.

Paintwork Inspection Must Haves

This brings us rather nicely onto the subject of this blog! New to UF, the Meguiar’s MT103 Sunlight 3-Plus Detailer Inspection Light is the latest addition to our machine polishing accessories range. It’s the perfect piece of kit for shining a light (literally) on exactly what kind of imperfections you’re faced with.

The second must-have item on the paintwork inspection list is one of the most innovative pieces of kit in detailing. The NexDiag NexPTG Professional is a dynamic paint depth reader which works in tandem with a dedicated app (on iOS or Android) to provide accurate readings that can be easily stored for future reference.


You can even store up recordings for specific vehicles (including the location on the bodywork) – it’s a feature that has proved very popular with professional detailers, enabling them to provide customers with a comprehensive report, both before and after machine polishing jobs.


Both of these paintwork inspection products are in stock and available to buy from us here at Ultimate Finish – check out the full details on both below.

NexDiag paintwork inspection

Latest App For Android and iOS now available

The NexPTG Professional is the most advanced model of the paint depth reading gauge from NexDiag, allowing you to make precise measurements on a multitude of places, including curved surfaces.

Thanks to the use of a movable head and a profiled probe housing in the device, the effect of vibrations on reading measurements on convex or concave internal and external elements of a vehicle has been eliminated.

The advanced technology in the Professional model means paintwork inspection measurements of an even greater accuracy can be provided compared to the Standard and Advanced versions.

The device also comes with the support of a dedicated NexPTG application which can be installed on iOS or Android devices. The application enables users to examine surfaces with unprecedented accuracy and thanks to the Lacquer Coating Analysis System, it can analyse the surface of the entire body in an instant with the application helping to interpret the results of measurements.

All measurements are easily recorded thanks to the application, including the location of where they were taken on the vehicle. The Professional also enables users to generate useful reports (including the ability to insert your very own company logo) based on measurement history and location.
