Panel wipe is a solvent used to clean body panels prior to application of professional coatings. This is important for two reasons. Compounds and polishes contain oils, which are there as a lubricant to help abrasive compounds move smoothly over your paint. However, these oils can fill micro scratches, making them invisible. It is important to clean the panel and remove the oils to inspect the paintwork to make sure the polishing process has removed all marring and micro scratches.
Secondly, it is essential that any oils are removed so that professional sealants such as ceramic coating and graphene coating can bond directly to the paintwork. Improper application of these coatings over silicones and waxes is the primary cause of coating failure.
