I need some wreck-omendations on high performance paint for corrosive environments.
Inb4 "rustoleum".

But pine tar is an interesting idea. I've heard of fuel tanks being coated in it.

Lacquer is usually used for "A" quality surfaces..like car fenders and hoods.
I don't care what the finish of this looks like.

Seriously need to know what material such as carbon steel, concrete, other etc., in what service/ environment and new or repainting (especially for prepping).
Best to engage a commercial or industrial paint provider and a professional contractor.

The part I'm waging war on is the cast iron torsion arm in this picture that are the axles of my boat trailer:
They are painted from the factory (NOT galvanized..I have no idea why), so after a few years in saltwater the rust is pretty substantial. Last year I removed the disk brakes, took a chipping hammer to the torsion arms, knocked off the iron delamination, wire brushed them, treated them with Ospho rust treatment, then painted them with silver Rustoleum.
It took about two dips in salt water for the rust to return. I'm going to do that process ONE more time. I will probably need new axles in around 3-5 years as the the rubber in the torsion bars is wearing out, but I don't want the rest of it to rust away before then. And I want to find something reliable to treat the next set of torsion arms prior to installation next time, too.

Getting real zinc paint is almost impossible now.

If I had some navy yard connections, I'd get some real zinc chromate primer/paint, but everything that's sold publicly is crap now.
I'm not sure PTFE would help, or how I'd apply it to stay on.

to reapply once a season. PTFE paints/coatings will dry and cure. Cajun folk down here use this chit called Gator glide on jonboats and fan boats. Hard coating that goes on the hull. If it ain’t getting wet, it ain’t corroding.

Kinda like fluid film, Boeshield, or anything of that nature--seems that would work well if it wasn't already rusted. I need to cut off any access to oxygen to keep it from rusting again.
I could put this on after I paint it though.

You're probably familiar with Cosmoline.....the stuff they put on the engine of just about every car that will make a trans-ocean journey post-production. Stuff works and is dammm near impossible to get off.

I think cosmoline, waxoyl, fluid film, boeshield, Lanocote are all similar
Jan 10, 2024, 11:25 AM

products, but just from the brief reading I did on the waxoyl that seems to be a better product because it dries harder. But like the other products I listed, I'm just not sure how much it seals from the air like a paint would.
When someone above reminded me of the pine tar I thought of using that, but that stuff is a mess..and it literally takes years for it to dry. It's used pretty extensively on below deck fuel tanks to keep them from corroding out. Which is a good application for that product, because nothing touches it, and it doesn't move, and is semi covered.
Cosmoline isn't one I had originally thought off (although I am familiar with it), but I'm concerned with its abrasion resistance. Best case I would do this job once, although I guess small touch up wouldn't be terrible. It's another that I think would do better on a nonrusted surface, but I could be wrong. Have you ever used to on something that you just wanted to keep "status quo"? Like "yeah its rusted a little now, but if it stays like that its okay?"
The pic below isn't mine, but it's not far from what I started with. Pretty heavy steel delamination; I gave up on a wire wheel and literally bought a welding slag hammer to chip off the delamination, then wire brushed what was left. The Ospho I used to treat the rust didn't do squat, as I had rust bleed through the two coats of rust oleum paint pretty quickly, so I'm not sure which product sucked more.

POR-15 was my first thought.
Jan 10, 2024, 11:05 AM
[ in reply to I'd hit it with POR-15 and then Waxoyl it.*** ] |
|
I've used it before, and had decent results I guess; I mean it didn't rust in the ~3 years after that I owned it. But it was only on a gas tank skid plate on a Jeep Grand Wagoneer. I never dunked it in salt water.
But then I saw this video, and POR didn't perform well at all. I was surprised. The problem with these axles is that whatever I put on there needs to seal the air out to keep rust from returning, but also needs to be abrasion resistant from road debris, deal with sand hitting it at highways speeds, weeds scraping it off etc. just due to being on the underside of a trailer.
Anyway, the Mastercoat performed well in the test in the video; I have ordered some and will give that a try. The real test is what I put on the new set of axles that I get in the next few years. Jacking up the trailer, removing the wheels, brakes, and hubs is a real PIA.

high performance, industrial type available coating that you might have experience with.
Back when I was in high school, my father had responsibilities for the maintenance departments at a few manufacturing plants. On anything that was seeing corrosive environments, he always had some kind of coating or paint that worked better than anything you could buy at hardware store. But then again, that was when "red lead" paint was made from lead based paint, and Zinc Chromate primer was actually made of zinc, and it actually worked.
I'll probably get cancer from all of it one day.
