Meguiar's M6301 Flagship Premium Marine Wax is a solid choice for those looking to protect their RV's fiberglass surfaces.

Users appreciate its ease of application, as it comes in both liquid and paste forms, making it straightforward to use even for those who might not be very experienced with waxing.
