Glossy wet look or matte satin finish — which should I pick?

It's purely aesthetic. Wet-look dressings like high-gloss sprays and gels give a shiny, freshly-detailed appearance favored for shows, while graphene and water-based satin dressings produce a darker, more natural matte finish that many daily drivers prefer. Several products let you build up coats for more gloss or wipe back for a flatter look.
