Aluminum and salt

I have a camper with raw aluminum sides -- and I can tell you that my winter and even shoulder months of camping is limited because I do not want to etch my beautiful camper.
I am looking at a couple options including wraps (which no one wants to do for me) and plastidip. The "Dip" has been discussed some, but always as a side item. I'm curious if anyone in the forum as actually used DIPYOURCAR type systems to encase their entire camper....or car.
Longevity seems to be the biggest issue --- but my camper spends its life in side a climate controlled garage how does this impact it? Also, I am looking at 'clear' rather than a tint, so fading shouldn't be a problem --- yellowing a nd breakdown maybe. But, if I can get 3-4 years -- 5-7 would be better --- it might be a great option...
Any experience out there?
