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

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

Works really good

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

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.

Used this for years..and its good but each time I come back to order the price has escalated. Cant justify the price of it now so this may be the last order, I ll move onto a competitor and get value for money. Sorry Dinitrol but you can only get away with so much good faith..

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

I’ve used this to convert rust on my Mx5. Seems to have worked a treat. Highly regarded by everyone it talk to. Only use it in well ventilated areas though, it absolutely stinks and can get down your throat. It’s very thin so will drop out of all the gaps.
