So I've got a 42 ft. park model in Grand Isle that we just got. I had a 40 footer that we've had down there for the previous 5 years and before that had it literally 50 yards from the beach in Constance Beach for 4 years. When I first got the 40 footer, I spent 2 days underneath it painting the frame with PPG 2 part epoxy paint. It held up decently for a while but being that close to the beach is brutal on metal.

Anyway, I moved it to Grand Isle 5 years ago on the bay side. The rust continued but not as bad as at the beach in Cameron Parish. I got underneath it a couple times over the past couple of years and pressure washed, scraped, wire brushed and sanded areas and repainted. The axles and springs looked bad, but they were still structurally sound when I sold it. I towed it to Houma and Galliano last summer for repairs and a tropical storm.

So, I don't feel like getting underneath that damn thing and painting this time. I'm thinking of spraying the whole underneath with an oil mixture and putting skirting around the bottom to keep the salt air and water off it. I've read that transmission fluid works well.

What do y'all suggest?

I spray mine down with WD40 a couple times a year and it looks pretty good. I use those ‘big blast’ spray cans of WD 40 and spray everything metal from the hitch to the rear bumper down with it, even the steps. It’s kept it looking pretty damn good and kept the rust to a min. My camper has been down there 4-5 years now. I’m 3 lots off the beach.
My camper does sit on concrete pad and under a cover also.

Consider using "Corrosion X", it is a product used to prevent corrosion in aircraft.

A gallon would probably do the job, and is $89.00, it is designed for your purpose, and since it is used inside aircraft the level of flammable chemicals in it are at a minimum which would also be a good thing for a structure you are living in.


"Use CorrosionX wherever you want corrosion control without paint or wax coatings. A light spray of CorrosionX on power heads, generators sets and engines a couple of times a year will keeping them looking like new – even in saltwater and coastal environments.

CorrosionX's unique formulation offers a multitude of advantages over conventional spray lubricants. Because it sticks to metal like a magnet, it cannot be easily displaced by pressure, friction or moisture. It lubricates under extreme loads and high temperatures."

Maybe some white lithium grease or fluid film would work and be long lasting?

Car undercoating or POR-15. They are both used successfully on cars that drive on salted roads. You'd just have to do it once.


That reminds me that I need to do the arse end of my truck frame
