## Description

This water-based, non-hazardous rust converter and primer effectively treats rust, creating a protective barrier to prevent further corrosion on various surfaces.

Review: The best rust treatment preventer. Final colour depends on treatment technique. - I have used various rust remover treatments but always come back to this one. Using it to touch-up areas on a car before painting has always gone very well. It is particularly tolerant of being painted over unlike some other treatments which make paint bubble ! I purchased the 1 litre container because it is more aggressively priced than the 250 ml but have found that I needed a lot less than I thought. It is not like paint, it has a watery, slightly creamy consistency and goes a long way. The only thing that did not go to plan on this job was the final colour. I have always painted over it before but on this occasion decided to treat my very rusty, poorly maintained fire-pit with Neutrarust before putting it away over winter (I am not really bothered if the finish burns off next summer). I used a course wire wool to prepare the surface then applied a coat of Neutrarust 221. This then turned my firepit blue and it ended up a very nice deep black colour with a rusty hue to it. I was very pleased with this finish. I had no intention of using paint over the Neutrarust so used a second coat, the following day, for extra protection. Again it turned blue but the final result is not as good as the first as it is now black with light grey blotches. I have decided to leave it as it is because I imagine it will weather and the colour will develop when the fire-pit is used again but I would only use one coat in future if repeating the task. Despite my experience if it is a treatment for rust you need this is my favourite because it :- 1] is the easiest to apply because it is not too viscous, water soluble, less toxic – it does not hurt if you accidentally get it on your skin; 2] acts as an under coat and tolerates over coating by most paints; 3] after one coat over rust it cures to a black colour which looks like you have painted the item black; 4] stops the progression of the rusting process This is my go to rust treatment and I will buy again.

## Questions & Answers

**Q: Will this treatment work on car chassis which are rusty ?**
A: Please see the instructions from the bottle label. Simple preparation!
Remove loose scale, flaky rust, all paint and dirt with thorough wire brushing. Reduce any high peaks of rust. Remove Acid, Alkali, grease oil and chemicals with detergent water wash then rinse with clean water. Paintwork blistered by rust should be scraped down to hard surface. DO NOT REMOVE all traces of rust. All areas must be adequately covered with Neutrarust 661®

**Q: Does this have a shelf life? Thanks**
A: I can’t be sure regarding shelf life, what I can say that it works well and after eighteen months since I first used it, there is plenty of life left in the remainder and no sign of deterioration. Just keep sealed after use, as it will thicken and dry if left exposed to air indefinitely.

**Q: can this be used for rusty heated towel rails in the bathroom?**
A: I’ve only used this on rusty vehicles but I imagine so. It’s important that you understand that this product will leave a brown coating on the surface it’s painted on. This is very very difficult to remove. I got some on my van’s paintwork and I had to very carefully scratch it off. This coating is to protect the treated area. Apparently it can be painted over but I haven’t got that far yet. 

As far as killing rust goes, it works brilliantly.

**Q: How many square meters will one liter cover, would it do the underneath of a LDV convoy?**
A: Hi. Neutrarust 661 will cover approx12 square metres per litre. And will work on the rust on an LDV

Excellent and works as it says

### ⭐⭐⭐⭐ Rust transformation
*by P***L on 6 April 2024*

Wow did not expect these results , it is expensive but boy does work , looked at many products. This looked the best . Try to clean with wire brush first , do not remove underlying rust . This product needs to react with surface rust , just pour into small containers, use artist paint brush and apply. Leave to dry , 24 hours , next day surface has turned black with Some White flecks . But all the rust has disappeared, fantastic .
