CHEMTECH Fertan Rust Converter 5L Metal Rust Treatment Paintable

Chemtech Fertan Rust Converter is a professional-grade rust treatment that chemically converts existing rust into a stable, paintable surface while helping prevent further corrosion. Its penetrating, water-based formula reaches deep into rusted metal, making it ideal for automotive restoration, marine maintenance, industrial equipment and general steel fabrication.

Unlike products that simply coat over corrosion, Fertan reacts with rust to create a durable foundation for primers and topcoats. It can be applied to lightly damp or dry steel surfaces and is ideal for restoring rusted panels, chassis, trailers, machinery, gates, fences and structural steel.

Trusted by restoration professionals worldwide, Chemtech Fertan helps extend the life of steel components by stopping corrosion at its source while preparing the surface for long-lasting protective coatings.

The economical 5 litre container is perfect for larger restoration projects, workshops and industrial maintenance where maximum coverage and reliable rust conversion are essential.

Rust Killer/Converter

This is the best product on the market, as long as you follow the directions you will get a great result, I've used this product previously on the rusted steel frame on a relocatable home and the results were amazing.

2 weeks ago sanded back top of the metal hulls back to clean metal on my houseboat followed instructions on how to apply fertan 18 hours later no ferric tannate waited up to 24hours no difference except a few rust spots showing up so had the people doing the antifoul paint the hulls with primer than antifoul waste of time and money( lesson learnt )

Does what it says!

I used this on my trailer after a rough wet sand blast. I didn’t remove all the rus, just the loose stuff. Sprayed Fertan all over the trailer and left for about a week and a half. Went black/blue. Hosed down with power washer, then when dry wiped with a rag to remove black powder. Just sprayed with hammercoat! Very happy😊😊👍
