A glossmeter is simple but invaluable tool when detailing. We recommend any detailing professional have this in their tool kit. Firstly, you can use the glossmeter to get an idea of the initial condition of the surface and the steps that will be required to restore the gloss and shine of that surface. We also recommend using the glossmeter to help determine if the surface is ready for a ceramic coating. We recommend shooting for minimum of 85GU on the glossmeter before applying the coating. Finally, we use the glossmeter to track the performance of the ceramic coating to ensure that it is performing as intended.
