Ok, so Fluid Film is good stuff, use it myself, but it’s not a substitute for painting. It does provide a decent , sacrificial barrier to corrosion, but if paint sticks to the metal it’s better. Fluid film is akin to oil spraying an undercarriage.
I agree with what you say, but the problem is that RV’s are built in a way that has frame, siding, etc. having crevices where one component meets the other. Salt spray gets into those areas and the never ending corrosion process starts. Fluid Film can be squirted into those crevices and is less likely to harm the various materials. Whatever you use, Fluid Film, motor oil, paint or anything else, you will never completely cover all the hidden problem areas and stop all the corrosion.
Make every effort to stay off the road with any vehicle while the roads are made unfit for use by salt and chemicals.
