I live on Padre Island (Corpus Christi end) and I have seen new RVs all but rusted out in a year if parked outside. A neighbor's entire exhaust system was laying rusted on the ground under his rig due to the salty damp air. I keep my car in a garage and the local Ziebart shop did a 'jungle job' on it as soon as I bought it. The RV won't fit in my garage. Any ideas about how to prevent rust on my yet to be built truck conversion?

Good Morning, Mr. Clu! https://www.truckhome.com/infopop/emo.../icon_wink.gif

I spent three years as a flight instructor with VT-28 at NAS Corpus. Prior to that I was the Aircraft Division and Corrosion Control Officer in an S2 squadron. Based upon my training and experience I would suggest two things.

First, protect all metal surfaces with an appropriate barrier (plastic was less in use in my day, but I would suspect it should be protected, too). Paint or wax or oxide, whatever is best suited to the surface involved. You might talk with commercial operators in the area and see what they use.

Second, perform regular and frequent fresh water washdowns. Use of soaps or solvents is problematical, in that they can remove some protective coats as well as the salt residue. Generally all you really need is water. I would be careful about using too much pressure (like a 1500 p.s.i. pressure washer) as that, too, can remove protective barriers by friction (vice chemical).

You probably already know that getting the unit under cover is the best protection. https://www.truckhome.com/infopop/emo...icon_smile.gif If you don't have a garage or pole building or something else you might look at one of the many "soft" covers on the market. Of course in the Coastal Bend be sure to tie it down REAL well so that it does not end up in your neighbor's yard (and that "flapping" of the edges does not abrade nearby surfaces). I'm sure you can find a retire boatswain (aviation or otherwise) to help you out, here!!! https://www.truckhome.com/infopop/emo.../icon_wink.gif

Corrosion control in a salt environment is a tough and ongoing problem. It's particularly bad in your area because of the constant, strong sea breeze and frequent heavy dews. But fresh water is your friend.

Good luck in your effort.

Thank you Smile for the correct washing process. I would have used soap forgetting its the salt with which I should be most concerned. My wife has come up with the ultimate solution- move off this hurricane target and go back to her home area in NC. I counter offer with OK but we have to get the conversion first that way we'll both be happy. Its nice looking out your front door at the gulf/sunrise each day but you are facing pending doom 9 months out of 12 and after over a decade of it, I'm beginning to feel like Ma Nature is saying 'do you feel lucky- punk?'.I suspect I'm about to become a Tar Heel.
