Newmar does an excellent job in adding protective coatings to the underside of the coach. First, before the base chassis is delivered from Freightliner the steel frame rails are coated. The chassis are covered when being shipped in winter months. Newmar adds the STAR foundation and then the entire chassis goes into a paint booth for a coating. After the basement storage compartment floor structure is installed, Newmar then elevates the chassis and applies a heavy undercoating. No short cuts. Adding another coating would not necessarily give added protection. Given that, you still have many metal components that will be affected by salty roads that just can't be coated. For instance the compartment door latches, entry steps, fasteners, engine/transmission components and other exposed items.
