Removing rust on an RV.
Removing rust from trailer frame. Using soap and clean water wash the trunk frame to remove any remaining rust dust. Give the trunk frame some time to dry off. Paint The Trunk Frame.
Apply a layer of a coat premier once the trunk dries. Apply another layer and wait for it to dry too. Paint the affected area and then later add a protective clear coat.
Whats the quickest way to get the rust off my trailer. Prepping rust for paint is most easily done with a chemical rust tranformer. Rust Transformer is one brand I think its made by 3M or carries the Rustoleum brand.
These liquids that are sprayed or brushed on chemically react with rust hardening and neutralizing it turning to a shiny black well bonded metal. Simply scrub off the rust with a stiff wire brush and then paint the exposed metal with a rust-inhibiting paint. For severe rust which covers a large percentage of the frame or has begun to cause pitting or scaling on the metal a body shop like Central Body Co Inc is your best repair option.
They will fully sand the frame to remove rust and smooth out any damage. Hard to access areas like inside seams etc get painted with Septone rust converter before painting. An extreme treatment would be to clean up the tup then get a coating like Rhino lining applied inside the trailer but would cost a bit to do.
Even the DIY cans of similar stuff arre 160ish at Super Cheap AFAIK. Depending on the condition of your frame axles and suspension you could easily spend an entire 8 to 10-hour day removing rust old paint or undercoating. Just like auto body work most of the effort is built into the prep process.
Where we had access we used a grinder with a wire wheel. If your Frame is covered. You said was sealed behind the belly pans.
I doubt there is going to be much if any rust. Most frames have been protected by powder coating. Those frames that need rust removal in my view would be the ones exposed to the open air.
Exposed to the road conditions. As you can see the frame is cleaning up quite nicely. The abrasive pads tend to get into pitting a little better than compared to just sandpaper.
A majority of this rust must be cleaning off otherwise it will come back and not allow the paint to adhere properly. Once satisfied we can move up to the sandpaper. And a Fourth type is a closed section beam which gives stiffness in 2 directions as well as in torsion.
This is a combination of all the above plus some. If you have a choice and want a lot of bang for the buck to stiffen and strengthen a trailer frame weld in gussets like this. However if you want to get the best results from using sandblasters to remove rust you should choose a sandblasting media that suits the task in hand.
The following sandblasting medias are ideal for removing surface rust from metal objects and components both large and small. Scrape off loose rust and paint rust with POR15 or use the phosphoric acid like Jeepsr4me said. Then paint entire frame with something like Eastwood 2k or Imron.
Then spray inside of frame with Eastwood rust convertor. Then before every winter spray inside of frame inside of doors inside of tailgate etc. With Fluid film or oil.
Its easy to use just a quick wire brush to remove loose rust apply the converter let it dry 24 hours and then apply a rust preventative paint. Or primer and then paint for even better results It works great and lasts a lot longer than just using just rust preventative paint. RUST is nothing more than signs that the metal is oxidizing slowly but oxidizing none-the-less.
Fire is rapid oxidization. SO if you got a FASTER truck the frame wouldnt rust but it would burn. I pass trucks rusting away all day long.

For example if youve found rust at the bottom of your bike frame you should apply the paste evenly at the bottom across the length of the frame.
Dirt and moisture get trapped inside the metal seams and bracing under the trailer and the rust they cause slowly works to the outside. There are lots of moisture and dirt traps under those trailers. The only way to stop this rust is to keep the moisture away from the metal by cleaning away the dirt and salt and using a rust preventative solution.
Cant galvanise a painted trailer without removing the paint first sand blasting takes care of this removes the rust where you can blast. Galvanising will only coat the rust if not removed. You can not blast the inside to remove the rust.
The point where the inside will rust the most is where the water line is when you launch the boat. Removing rust on an RV. If rust has formed in a tiny area use a stiff wire brush to scrape it completely off.
Then cover the exposed metal with a rust-inhibiting paint. When there are larger areas of rust or when its on the RV frame a professional body. Unfortunately this is a tube style frame so there really isnt an efficient method for removing rust in the inside of the frame.
Im just using this tubing as an example while it can be painted on the outside its tough to do so on the inside. Several methods are available to remove rust from exterior metal. Using a power tool such as a flap disc fiber disc or a sander on a flat area Application of rust removal chemicals containing phosphoric or hydrochloric acid Application of newer non-toxic and acid-free chemicals that dissolve rust through selective chelation.
