Stopping frame rust, product suggestions

[JustDandee]

Helping my son out with his new purchase- 2000 suburban w/supercharged 6.0. Its out if Salt Lake City area so its got some frame corrosion that I would say looks fairly treatable.

My idea is to spray down the frame/axles/spare tire carrier etc... with a neutralizer/reformer and then colme back in a week and paint these areas. maybe fluid film as a third treatment?

Suggestions on the good stuff? I was thinking naval jelly originally but I think a spray would be best to try to get best coverage and a spraying into the opening's.

what have y'all tried?

There are long threads on this with lots of ideas. I'd dig them up, but I gotta go right now and there is a search feature. Best of luck. IH8RUST

Have you looked inside the frame with a borescope? Basically if you have heavy thick rust or especially flaking there really is no "treatment" as far as I know without mechanically removing the heavy loose stuff first first. After that the solutions are based on how much rust you have and where it is.

For guidance the frame looks something like this at its worst spot..note not the actual vehicle.

Rustmort looks like a really good product, but not sprayable. Rust reformer by rust oleum is sprayable. Anyone used that And satisfied with the result? Still poking through the search bar for more ideas.

On a C-channel frame like that I would use a sandblaster/wire wheel/ etc to manually remove as much as possible then get it washed as clean as possible before ever applying a rust reformer. Unlike the frame on the TJ you have pretty fair access to most spots. The more rust you can get blasted off mechanically, the better chance the reformer has of penetrating and stopping future rust. That is how I would approach it anyways.

That sounds like a good plan. Do as Cornbread said above and mechanically remove as much as you can, however you have to do that.

For a converter/reformer I’ve used SEMs Rust Mort in the past https://www.semproducts.com/product/rust-morttm/morttm It works well, but it will eat into concrete so just be aware of that.

For paint, I'll suggest Eastwoods internal frame coating for getting inside of cavities/channels/box sections (very runny, will get everywhere, especially on concrete). For exterior paint, I like Rustoleum rusty metal primer and a top coat of your choice.

thanks, I went down the rabbit hole on searches- lots of products- but as you said cleaning what you can off seems the best.

shes just a big vehicle and being newish there will be a lot of tight/inaccesible spots on top of the frame, torsion bar cross support area, around the fuel tank, etc.

thinking something like using a corraseal product for the easy to get to areas and something like the VHT to spray in the areas we can get to.

Loosen the body mounts and lift the body up a few inches. You can space it with some 2x4 chunks.
