To achieve the durability and performance benefits specified for quartz coatings, it's essential that the surfaces to be treated are properly prepared in advance (in a nutshell, the cleaner the surface is, the better the coating will perform and last). Gyeon Q²M Prep is the perfect product for this task, as it ruthlessly strips all traces of oils and polishing residues. Furthermore, it also imparts an anti-static finish to treated surfaces, which helps to prevent dust from settling out and interfering with the coating application process. This product is seriously good, and far more effective (and nicer to use) than other alcohol-based cleaners.
