Rust Protection?

Hi everyone,

Firstly - we have upgraded our TT! (see new profile pic). We decided after 18 months that we need the additional room provided by a slide for our growing family. We liked the overall (24ft Hideout 24BH) length of our previous unit, so stayed similar length this time. Our new unit is a 2015 Passport 2400BHWE. Have done 2 short trips so far and love it!

My question is related to TT frame rust prevention. Our trailer was built in November, so likely it was towed to the dealer on salty, winter roads from OR to Canada (AB). For that reason, we have quite a lot of surface rust on the frame, including all of the fasteners (which seem to be metal self tapping screws) which attach the "enclosed" underbelly material to the frame. The dealer did an "OK" job at cleaning it up prior to delivery, yet still there is some quite substantial areas (particularly suspension) which are rusty.

Firstly, I did search the forum and I understand that this is mostly surface rust and won't affect operation. That said, it does look terrible and i'd like to spray some kind of penetrating spray over the metal components to stop any further rust development and help keep it looking better.

I found a new WD40 'specialist' product called 'corrosion inhibitor'. I have used WD40 successfully in the past to help prevent rust, but has anyone used this corrosion inhibitor product specifically? Any suggestions for other rust prevention type sprays? I'm looking for something that will penetrate the rust, and help stop it getting any worse.

Thanks!

I have experienced this on previous trailers. I found it best to clean the areas and hit them with a coat of Rustoleum glass black in spray can. Very easy to do but should wear a respirator if working under the trailer while spraying.
After in initial coating, just repaint and touch up as needed.

I made the mistake one year of driving with my old TT after the roads had been salted (in wonderful western NY) as I needed to get it in storage ASAP. What a mess the next spring since it was never cleaned off right away. I used Eastwood Encapsulator to basicallly paint over the rust (after wire brushing off the worst stuff) on the frame and other components. It is supposed to go over rust and stop it from spreading. I cannot speak for long term but for the few years I had the TT it held up well. The stuff is not cheap and it takes a ton of time to 'paint' everything but it could be an option??

Thanks for the suggestions!

I did think about Rustoleum spray paint in gloss black, but guess it sounds daunting at first, so wasn't sure. Did you just paint the frame only? Any suggestions for the leaf springs and suspension components? The rust is also covering the drum brake housings, which looks awful.

I have the exact same problem, up in northern ab too. I cleaned it off as best I could with a brush and some good water pressure then let it dry overnight. Sprayed it with gloss black rust paint and it looks a million times better. I can't speak for how long it will last but I suspect It will be part of my spring maintenance routine to hit the spots that start to look ugly again. I also hit the box for my entry steps it looks a heck of a lot better now.

I probably use 1 spray can of Rustoleum each year. Frame, pin box, rear bumper, steps, frame, suspensio, axles, etc. It keeps everything looking nice. Just need to clean all good first.

Like others, I always wash the frame and suspension well, let it dry, then get under there with a can of Rust Oleum - do one real thorough job a year, then get under there when I have a nice day and feel like it whenever I think a touch up is in order. Instead of the regular semigloss paint, I use http://www.rustoleum.com/en/product-.../rust-reformer which is more of a flat black, but seems to stop the rusting a little better .

Thanks for all the responses.

An update - I got underneath one evening this week with a wire brush and removed what I could see of the rust, then water blasted it down, let it dry and have hit now it (in patches) with the black rustoleum - came up great! I was surprised how easily the black paint just blends with what's there... it all looks "new" again

Happy Camper!

Just to let you know. The frames are transported uncovered, slacked up on open flat bed trailers, than uncovered they sit outside the plant in Pendlton for who's knows how long. And likely they where only painted with what is cheap paint and fast as possible. Oregon does not use salt on the roads ODOT uses a liquid anti freeze. I cannot say what was used on other state highways. That anti freeze can stain unpainted surfaces and leaves a oily film on painted surfaces that is flushed away with water.

This is the way frames are transported (stacked 4 high with the bottom one on wheels) and how they are stored at the Indiana factory.

I have kept the frame of our TT sprayed with a light coat of fluid film.

I kill the rust first with Rust Kutter (spray bottle) from Tractor Supply. It stops the rust and turns it black before it gets out of control. An auto body buddy of mine told me about it.

I don't see any reason not to paint the springs. I give mine a shot of spray paint just about every year.
