![]() The clear coat has a thickness of 60 micrometer, which means you can polish up to a maximum of 6 times until you run out of clear coat. For the sake of this example, lets say this is 10 micrometer each time you polish. To remove the imperfection that made you decide to polish, you need to remove the amount of the depth of the deepest imperfection. The clear coat has a thickness of 40 micrometer.Įvery time you polish the surface you will remove a very fine layer of the surface. The colored coat has a thickness of 60 micrometer. The primer has a thickness of 20 micrometer. You have been able to measure this with a paint thickness gauge. The thickness of your paint is 120 micrometer. Eventually you’ll run out of paint to work with. So every time you polish the surface, you remove a thing layer. The downside is that you can not re-apply the paint you remove. The amount you remove should be equal to the depth of the deepest surface imperfection you are trying to remove. When polishing, you remove a very fine layer of the surface. 2 Impossible to name 1 minimum paint thickness.A detailer looking to correct swirls and surface scratches will typically be working on polishing the clear coat layer. Modern automotive paint systems are multi-layer and typically involve application of a primer, followed by a colour coat, followed by a clear coat. Our paint thickness gauges have these features. Likewise, compactness provides for the ability for the user to slip the gauge in or out of a pocket during work.īuilt-in sensor probes and an automatic measurement function allows for one-handed usage, which can be particularly useful when measuring at awkward angles or when reaching across bodywork. Portable, handheld, lightweight paint thickness gauges are necessary given the mobile nature of most detailers work and the range of surfaces that they need to be used on. Furthermore, the gauges automatically detect the substrate type without the user needing to switch between modes. Some low specification gauges can measure on steel but not aluminium and vice-versa.Īll of our paint thickness gauges can measure paint thicknesses on both steel and aluminium car bodies, through magnetic induction and eddy current technologies respectively. Measuring paint thicknesses on these metals requires different technology. Versatility across different car bodiesĭetailers work on cars with both steel and aluminium bodies. Our paint thickness gauges measure to a resolution of 1μm (micrometre = one one-thousandth of a millimetre) or on our flagship FN CM model, to an even higher resolution of 0.1μm. Low specification gauges may read to a resolution of no less than 10 micrometres or worse. Likewise, an appropriate reading resolution is required to be able to determine levels of material removal. They may produce erratic readings that lack consistency, meaning the user cannot assess the level of paint that has been removed during the polishing process. Low specification gauges are not suitable for detailing purposes and use during machine polishing of paints. It is important that a gauge used for paint correction has appropriate consistency between readings and measurement resolution. The majority of our paint thickness gauges feature a memory function. The process of mapping a panel or vehicle can be eased and sped up by using a gauge that has a memory feature, allowing readings to be automatically be stored. If polishing paint without a clear coat, such as cellulose paint, the risk is of striking through to the underlying primer coat or even the substrate metal. For example, removing too much clear coat can strike through to the underlying colour coat or even leave such a thin layer of clear coat that it fails and subsequently flakes off. The risk of beginning to polish paint or continuing to polish paint without undertaking such measurements risks striking through the paint and requiring an expensive respray. Likewise, measurements can be taken during the polishing process to assess levels of paint removal (which can vary based on different paint hardnesses and polishing compounds and equipment). This allows the user to assess safe thresholds for material removal and identify and potential prior repairs. Before beginning the polishing process, it is important to assess and map the thickness of the paint across the areas to be polished. ![]()
