For many years I wondered what the best way is to treat rust, especially in areas where you cannot always remove all the rust..<\/p>\n\n\n\n

One thing that never made sense is how manufacturers can advice people to use water based products as a solution to trust. Rust is formed on a metal when oxygen and water is present. If you can remove one of these 2 elements you will not have rust. <\/p>\n\n\n\n

Especially when restoring or fixing old cars. You always have rust which starts to form inside the doors, fenders, A-Pilars, etc. If you can treat and stop, or slow down, the rust you can extend the life of the car without having to cut and weld. <\/p>\n\n\n\n

The last thing you need is a product with false promises. Imagine you trust the online reviews and trust a product, you paint all the difficult to reach spaces inside a car, just to find that the product actually excellerated the rust, not stop it. If you treat rust inside a car you need to be sure that it will be stopped or slowed down.<\/p>\n\n\n\n

I was looking for a good rust converter and one product kept on showing in the top 3 results of online reviews. I decided to import some of it as I could not find any in South Africa. It was touted as the best rust converter on so many web sites that I did not even think twice. When I received it I immediately started to treat my old Ranchero which I know I can only start restoring a year from now and I just wanted to slow the rust down during the waiting period. <\/p>\n\n\n\n

To my surpise I saw light brown corrosion forming in the area which I treated the next day and I realised this product was nothing different from other water based corrosion treatments.<\/p>\n\n\n\n

So I bought 10 other paints, primers and rust converters. I was looking for products which claimed that they convert rust, prevent rust, is a primer and top coat in one. The typical “Direct to Rust” solutions.<\/p>\n\n\n\n

The only exception was Duram NS5 etch primer. It is my favorite etch primer. It does not claim to prevent existing rust and it clearly state that it is only a primer and needs a top coat to be effective. Yet it outperforms many of the so called rust inhibitors.<\/p>\n\n\n\n

The products used in the test were (I added their claim in brackets):<\/p>\n\n\n\n
