WhO's THE BEST, rust remover/ encapsulator Options

[mrgjones]

Alright. There are a lot of products on the market that promise to remove rust and prevent it from coming back. From reading the threads it seems the opinions on this forum are as varied as the products themselves. This thread is about making a convincing argument... or a ludicrous allegation, which ever you find appropriate. Horror stories are welcome but please limit yourselves to the chemical rust abatement theme already established. For you slow starters, here is your motivation.

...I took my body down to metal and treated it with Phospho four years ago, and still no rust on any of the treated surfaces.
It leaves the surface a medium grey.
The car has been on jack stands in the garage which is vented to outside air....I live in South East Florida, so the humidity ranges from 80 to 100% !
I have also used Metal Ready, after removing all rust physically. I have used it also after I have cut out pitted areas and replaced with clean metal.
I pefer to Phospho and epoxy primer over clean metal in preparation to get maximum delay in rust. Noticed I said "...maximum delay."
I trust rust converter, like I trust the curing properties of bear shit smeared over a wound.
There are better people and methods...I would ask Scotty B, if I were you. He massages a larger cross section of cars than any of us.

Good point - there are many interpretations of the phrase 'rust convertor.'

When I wrote my initial response, I used it in the sense of 'reduction chemical reaction' which is what the acid products do - chemically replace iron oxide with something else. (Reduction is the opposite of oxidation.) So you're using the magic of chemistry to get the oxygen out of iron oxide.

The phosphoric acid stuff liberates the oxygen and in turn promotes the formation of iron phosphate, in addition to the zinc (an excellent corrosion inhibitor) and/or manganese phosphates present in the chemical. (Parkerizing, a large-scale rust-inhibition process, uses basically this principle.)

So that's what -I- mean when I talk about a 'convertor.'

There's a bunch of Magick Shytte products that like to call themselves 'convertors' and I agree when Dave on his assessment of their curative properties. They basically 'convert' the rust from rust you can see to rust you can't see. For at least as long as the product warranty, the terms of which seem to depend on all manner of impossible-to-attain conditions involving the dark of the moon, eye of newt, and hair of frog...
