Rust Converter
Just wondering if any of you out there have ever used this rust converter found at RustGuy.com | Industrial Strength Rust Control Products | As Seen on TV | Permanently Stop Rust If it works as advertised I might take a day and “paint” some leaf springs and other parts that could use some TLC. I called the manufacturer and he stated that the inhibiter will work on flexing metal as well and it won’t come off. I have searched other threads that discuss POR-15; however, I have not seen any feedback on this stuff.<O

Dan, the only way to get rid of rust is to grind it, media blast it or such. then you need to apply a coating to stop oxidation. Any rust will return, and all these rust conversion products are temporary. For under your truck, try usings things like Fluid Film that you apply as needed. I once used a spray for braided steel cable that I got from someone who worked on a tug boat. That stuff was great. A lot of rust removal products are, or contain acids. try putting muratic acid on a piece of rusty metal. cleans it real nice, then watch as the surface rust returns. The same day if its humid. just my experience.

I have heard nothing about that particular product but I have used the Permatex stuff. But that does need to be top coated to last. It does indeed stop light rust though. I have used it on my oil pan and on a camper frame and it has held up well to 3 winters now.

I have been using Rust converter for years and love it.
In California the only rust on vehicles is coming from driving them in other states, do I don't have to worry about it too much.
Here is a picture of steel beam I keep in the open and trying to sell it -sprayed rust converter on the end. You can notice how the rust got converted into a protective coat. The coat is not permanent and should be painted for permanent protection.

The term rust "converter" is quite misleading. Nothing will convert rust back to steel, it has oxidized and been destroyed.
Sanding and grinding or even wire brushing rust away is the way to go. Take it down to bare metal, then cover it with the coating of your choice. As long as your coating is air tight, the rust will not return.

Yeah I was very skeptical about that stuff and it has worked well on my pan, which just had light surface rust. Scrapped a bit of it off and hit it with the permatex and haven't had any rust since. Worked well on my trans pan too.

Our rust problem in SOCAL does not come from salt on the roads as much as it does from salt in the air that comes in off the ocean every night. The first three years I owned my truck I lived on the beach front so I have some surface rust but not any serious rot like others may experience in other parts of the country. I think I will be the test guinea pig on this one and order a small batch and see what it does. I have undercoated my truck a few times so I don’t have much but the rust on the leaf springs and other small places drives me crazy. I know a truck is supposed to look well lived in but I would like to get another 20 years out of this one.

I buy some rust converter at the local hardware store. Back in 1989 I converted some rust under the back seat of my Falcon. I then painted over it. 20+ years later it's still rust free there. It works by converting the iron oxide into a paintable polymer. It's a chemical process that goes right down to the existing steel if you don't try to go through too much rust. The stuff works, and the only prep you do is make sure it's free of grease and not too thick of rust. A wire brush before hand is all you need to do to make sure it's not too thick.

Not trying to argue here, because I'm no wize, but I don't see how a chemical process turns iron into polymer, plastic. Isn't it more likely the product is polymer based and is sealing the surface? Again just asking.

Not sure how it works. I do know it converts the rust down to the steel. If it only covered it it would eventually bubble up and peel off. It doesn't.
I did ask my Plasma Physics professor if she knew and her eyes lit up and said, "oh it must..." and it went right over my head. I can ask my dad. He has a degree in chemical engineering...
