Ceramic Exterior Surface Treatment
We just bought a new full body painted fifth wheel. I will be checking out the new ceramic coatings to at least apply to the front cap. There are several of these products now available that last form 1/2 to several years depending on the product and how much effort it takes to apply.
I do not know if the current EcoRVPro treatment uses this technology, but if it does you can expect superior protection for longer than any kind of "wax" coating...not only paint protection from the elements, it also has some "armor" characteristics.
I worked in the aerospace industry for many years. I have personally seen a product from Cilajet being used on aircraft to seal the paint. Their product is a ceramic based coating and is now available for marine and automobile use. If it is good enough for a Boeing 787, it will be more than good enough for any automobile application. But again, there are now many companies offering ceramic based products, so I am sure there are types that can be applied just like a spray or wipe on wax treatment.
