Rustbuster FE123 & Granville Rust Cure – Shocking Update 2016


*** Shocking Update September 2016 ***

It has been a few years 2013/2014 since I wrote my reviews on both of the products FE123 & Granville. I have kept the same test piece of metal out in the sun & snow as well as everything else in between. The metal was a splash guard from under a front fender which was left around the back of a shed. I decided to have a tidy up and get rid of it. Then I thought I would share the findings. To keep things fair I will post this at the bottom of all the tests for Granville & Rustbuster.

I am expecting a torrent of abuse over this because I haven’t done this or that. But the products say they convert it and protect it not me see their pitches below;

FE123 sales pitch

“fe-123 envelopes rust at a molecular level, developing into a neutral layer which exists between the steel’s surface and the atmosphere. This neutral layer prevents the migration of ions so that no chemical reaction can occur at the metal’s surface. Recent independent testing by ‘PRACTICAL CLASSICS’ magazine April 2011 proved that fe-123 not only converted the rust but also left a foundation that could be painted over without neutralising and came BEST IN TEST scoring ten out of a possiible ten ponts. If you would like a copy of the report you can down load from the top of this page. We where also awarded best in test by CLASSICS MONTHLY in there 2011 long term test results.”

Granville Rust Cure sales pitch

“Granville Rust Converter is the rust convertor used by the oil and marine industries, the MoD and NATO.

It is used to stop corrosion in environments far more severe than your car will ever see . . . and it WORKS. Drying to a tough gloss black finish it can then be top coated with most paints. Environmentally and ecologically safe. Acid and lead free. Non-flammable. MUST be applied to rusted ferrous metals. Kills old rust and stops new forming.”

  The update on both of these products is not looking good.  

I have not coated these converters with anything else at all since it was all done way back then. The results are there to see for yourself. It says on all these things it forms a barrier and coats to protect etc etc. I am not convinced let alone impressed.

You can look closely you will see the untreated areas are brown with rust and the straight edges. Rustcure is on the left, FE123 is on the right just before the white sticker.

Here is the test I compared myself click here or  https://onemanandhismustang.com/rust-comparison-test-granville-vs-rustbuster/  I even done a few videos on the products on my YouTube channel click here or follow this link https://www.youtube.com/user/OnemanandhisMustang

You can see from that comparison exactly where I have added the products either side of a piece of electrical tape that i removed after application.

The rest of the metal?

It’s clear to see that none of it has worked left uncovered or painted.

BUT….

On the right there is a black piece of paint that I did at the same time out of my own curiosity, this has NOT rusted.

rustresult6

The black paint? That paint is POR15. The paint which was applied incorrectly with only one coat and not two like recommended, without treating the metal with their three step process, it has still outperformed the other two liquids.

Conclusion:

Now you may say it’s unfair of a test etc. So I challenge Practical Classics magazine to show you, the internet or me their results after 3 years. Did they paint over it? I don’t know. However; neither was the POR15 and that didn’t rust in exactly the same conditions. I will let you make your own minds up.

For me there is only one cure for Rust – New metal!
