I have some surface rust on my van. Mostly on the bottoms of the doors and rocker panels. Sherwinn williams sells some industrial oil base paint I am thinking of using.
This is a work van, aside from rust I do not care about the looks. Is there some sort of paint that will stop the rust. I did the whole grinding priming and painting one time before. Now it is starting to come back. There has to be some sort of way to slow this down more. Maybe I should be using some neutralizer or something.

Rustoleum Rusty Metal Primer and their top coat. No need to get to crazy with prep either. Give it a quick wire brush and a wipe with an appropriate solvent. Lasts a long time too.

Gets good review. This sounds like just what I was looking for

Since you're not going for perfect looks, have you considered plastidip spray right over the surface rust that's showing?

Their is an area under the spare tire that has surface rust. What do you think of using muractic acid first?

There are various rust converters. Rustoleum makes one called rust reformer. I dunno if it is an acid or what. But it chemically reacts with the rust and makes it into something stable and paintable. I have not used this. I think maybe it takes a long time for the reaction before you can paint? I'm not sure. But I like the idea.

I usually reach for red oxide primer. It is made out of rust. It has a red color. It's great for sealing up rust because it is already rust and it can't rust any more.

Brush with Ospho rust converter. Let it dry, then paint (Ace Hardware sells it in small containers.


Do not get Ospho on concrete. It WILL eat into it something fierce.


I used this on an old rusty car and it worked like magic.

Tried the Rustoleum stuff, and it just didn't do very well. I'd call it a waste of time.

I appreciate what everyone is telling me. I plan on buying one of everything and seeing what works, what lasts. I can also farther research what is giving good results.

I want to fight this rust. Many tradesman just buy a less rusty van every 5 years

Got a picture showing how bad the rust is?
