Cost: £12 – £15 for 0.6kg
I am always looking for the ultimate rust protection for my car, I have tried endless treatments in the past and all have been rubbish, The last couple of years there seems to have been a major step forward with the treatment of rust. The big players seem to be POR, Granville and Rustbuster. This review will look at the Rustbuter FE-123 as a product. I have compared the products via my YouTube video for the results.

I tried and wanted so much for this product to be great. I have attached the PDF of the of the Practical Classics Article.

What’s In The Pot:
The pot has a single label on the front that says how good it is and that is basically it. The label goes on to say that it can be diluted up to 50% in order to make it into a cavity spray. and that is a great idea. Suggests this stuff is supper strong. There are no storage suggestions for the product.
The application is done via a brush, this rapidly turns the rusted area into a black treated area that will protect the metal or molecularly convert it into a safe metal again. A single application of the milky type substance is all you need.
The coating creates the transformed material into a black metal again. I treated a sheet of metal that I left in the garden for a coupld of months doing nothing else to it. By the side of it I also painted the Granville Heavy Duty Rust Cure. After a period of a few weeks the FE-123 started to peel and crack of it’s own accord. I managed to lift part of the coating off and left it. I also did exactly the same to the Granville.
My leave it in the rain and the sun test has allowed the rust back through the treated area. I was absolutely gutted as I bought a litre of this stuff for around £40. I wanted this stuff to work. It has been given winner awards and yet NOBODY is showing you the results later on from the initial test. I DO, and I made a video of it as well.
I have inserted some photo’s of the test metal and marked with arrows the peeling coating and the rust spots coming back. The last two pictures are a close up of the FE-123 with the rust spots that don’t need pointing out!
Rating: 3 out 10
Why so bad? more like I was generous. I held the rust at bay for a few weeks, there again so will WD40. The coating split and the rust is back. As far as I am concerned left in the open for a year or so and it comes back – well maybe. Most of these cars go into a protected environment to be fair. So it shouldn’t make to much difference. BUT, when the product next to it is still as it was at the time I treated it – something is wrong.
Would I recommend it? If it was a real cheap bargain then yes for the shed hinges.
would I buy it again. No.
Granville is the same price basically and it is a far superior product. Granville is used by MoD and NATO, Rustbuster can’t claim that can it?
*** 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.
Here is a similar angle of the updated results:
The original second batch of tests
Again taken from a similar angle for the updated results:
The rest of the metal?
It’s clear to see that none of it has worked left uncovered or painted.
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.
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.
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!
