Best way to protect an RV frame in Grand Isle?
Posted on 9/21/18 at 5:29 pm
Posted on 9/21/18 at 5:29 pm
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.

Ours isn't under a cover, but it's on a limestone driveway (sucks to have to crawl under it in limestone).
I noticed that the top of the main I-beams where it was protected by the aluminum siding of the RV was in good shape, and the bottom of it had alot more rust. I think a skirting from the ground to the top of the I-beam would help alot also.
Seems like WD-40 would be too thin to last. That's why I've heard good things about transmission fluid.
And I'm removing the stairs and bringing them home. I have a 6x5' deck and stairs that I put in front of the sliding glass doors and wooden stairs for the bedroom door.

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

Gonna look into it bro, thanks. 
Can it be sprayed or do you have to paint it on?

It is usually sprayed on, aircraft people sometimes use a set up like this, but it is kind of pricy.

But some use just a pump up garden sprayer from Lowes or Home Depot, the only disadvantage is it sprays on pretty thick and will drip a good bit.
I have not tried it, but if you have a air compressor , a cheap paint gun from Harbor Freight might be the best option.
Keep in mind you want the "original" formula, the Corrosion X HD is too thick to be sprayed.

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

Bed liner or car undercoating. More work and cost but almost maintenance free.
Posted on 9/22/18 at 2:13 pm to bhtigerfan
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

Move it.. seriously good advice. Had mine down there from feb til Labor Day. Looking to do some stuff also

Get one of those mosquito misting systems that is on a timer. Fill with WD40 and have it go off every week or so. You could also try sacrificial anodes or copper based boat hull paint

This or rubber coat/ bed liner.

I second the por 15.
You'll never have to touch it again.

Gonna check out the POR-15 also.
Thanks everyone.
Thanks everyone.

if you use por15 make sure you follow their system for prep. also be sure to put finish coat on at proper time. if it dries too much you will have to sand primer to get finish coat to cover properly.
