Of all the different ways to deal with rust, this really leads the pack!
I first saw the use of rust converter some years ago in a metalworks industry
estate in the western part of the island. My response at that moment was : "Geez, why are you applying milk onto the air-con ducting?’ Good thing those words were uttered only mentally, not verbally. That was my first encounter with this amazing product - the Rust Converter.
The milk-like substance, upon contact with rust, first turns the rusted surface blue in colour.
After about 15 - 30 mins, the rust is converted into a black-coloured protective coating that is inert to further oxidation.
Red lead or red oxide primer act differently by covering the rust with a coat of oxidised paint while rust converter actively reacts with the rust. Once the inert black coating is formed, rust is arrested. The metal can either be left as it is, or top-coated with a alkyd, epoxy or polyurethane paint.
The advantages of the Boatman Rust Converter are:
- it can be applied directly onto rust with minimal preparation
- it’s non-hazardous, non-toxic, not flammable
- it’s water-based and easy cleanup (environmentally friendly)
- it’s extremely easy to apply, with brush or roller, or even dipped
While the practical coverage depends greatly on the extent of rust, 1 litre of the rust converter can cover approximately 10 sq m. It dries in 15 - 30 mins but should be top-coated only after 4 hours.

“1 litre of the rust converter can cover approximately 10 sq m.” That’s it?
I know a product Rass-O’-Nil that covers a lil more than 300 sq. mt with just one litre. And the corrosion protection is top-of-the-line. You should try that.
Thanks Viju for the info.
I went to their website :

Their stated coverage is 2000 sq ft per gallon which works out to about 50 sq m per litre. Still, much better than Boatman’s.
Any idea what the cost is per litre?
Am not sure, but I think it’s about $ 115 a gallon.
Thanks, Viju
