Dinitrol RC900 400ml Rust Converter Paste for Metal, Ideal for Converting Rust before Painting

I used this to treat the rust on my Alfa Romeo Brera (I know yes, surprise, rust on an Alfa...). Wire brushed it all down and treated with this to convert the rust then used a spray on wax, like Bilt Hamber to protect the metal. This stuff works perfectly, must let it dry, around 6 hours between coats but the one can did most of my under carriage. This stuff comes highly recommended as an alternative to other products.

Small hole caused by rust in foot well of defender 110 with some rust around the hole. Wire brushed main rust but left some for binding used dinitrol which left a strong rust free surface to enable filling and spray painting. Great stuff

Very effective rust killer and primer, expensive but works extremely well

This is a good product, have used many times before, even though its expensive, it really is good. Ordered for prime next day delivery, but took 6 days , due to seller choice of Royal mail who lost it. But in the mean time 7 days ive done the job, but seller what me to pay for returning postage, wouldn't use seller again

Must have used 10 + can of this stuff over th eyears

Very good product with exceptional quality.

Spray into cavities before cavity waxing if in any doubt about existing rust.

made a really good job of my motor and saved a lot of money I .will see how it winters.
