Review: Miracle worker for rust treatment! - This product is amazing. It converts rust into a solid, paintable surface in minutes. Very easy to apply with a small brush and a little goes a long way. Saved me a lot of time on car body repairs. Highly recommended for any DIY enthusiast!
Review: Will save your old car's rusty panels. - I've been using this since 1987 and this is the best stuff you can buy to stop rust on a car. When you open the lid it looks like white milk and smells like sour milk but it dries clear/almost transparent black color so is perfect for all types of rust on all types of paint. When you apply it to brown rust it will look like white milk but after its dried it will look black, any over spill on to paint will look almost transparent black color. In normal warm dry weather it can take around 15 - 20 mins to go hard but in colder/damp weather it can take longer. Once dry you can fill the panel's rust holes with body filler and paint it. It can be applied to all rusty services and when dry will strengthen the rusted area it a bit. It can be applied to dry and damp surfaces and works perfectly but on damp services it will take longer to go hard. In warm, hot weather this will dry faster than in cold damp weather. In general its best to apply 2-3 coats, so you put one coat on let dry and put the other coat on after that, that will give the best protection. Its non toxic so if you get any on your fingers you'll be ok. When you've finished using it, you can wash the brush in water and the brush will be clean. Although I've used this to save my car's rusted panels, it can be used on anything rusty. Each bottle of this paint is as good as the last one, so you can rely on it to kill rust. I feel its the best anti rust paint you can buy because once you've painted the rust then 9 times out of 10 the rust will never come back. If it does come back as a new rust bubble then you just paint more of this stuff over it and it will fix the rust. I highly recommend it.

## Questions & Answers

**Q: Can u use this on bicycle wheels**
A: If you have steel rather than aluminium wheels then it is ok. Rub off the loose rust and then apply the hammerite. After a day you can clean off any remaining hammerite. Then you will have to paint the wheels with aluminium paint. Try to avoid getting the paint on the tyres. It will be a bit time consuming but should give a good result.

**Q: Hi all.  Was wondering what the whole process would be to make my 15 year old van rust free underneath? Prep rust, use rust remover and then paint?**
A: Hi, this is not the best product in order to rust proof your vehicle. This is designed for small item to be finely applied. As per another answer I gave the consistency of this will also not apply well to a vertical or hanging surface. This will also not prevent further rust rather convert only what is there. An online search will find products and services that will apply better and do a much better job for a vehicle.

**Q: Would this work on the springs of a garden seat?**
A: yes it will work on any thing that is iron or steel .

**Q: Can you use on baths**
A: I do not see any reason why you cannot, however it would be better to get the bath renammeled.

### ⭐⭐⭐⭐ Great product, applies easily, dries quickly.
*by M***N on 7 June 2023*

I bought the 500ml version of this product. My plan was to use it on metal garden chairs that I've had for nearly 14 years, chairs that are now beginning to show signs of rust. The chairs were expensive in the first place, and were made from a chunky wire-mesh grille material that had been powder coated and supposed to be weatherproof forever. However, in Scotland, nothing is weatherproof for ever, and these chairs had slowly developed a brown discoloration that was a clear sign of rust getting under the powder coating. I painted them last year with standard Hammerite paint, but the discolouration has returned again this year. With the benefit of hindsight, I should have used this Hammerite Kurust first. However... This Kurust paint is pale blue in colour, but deepens to a dark blue once it has converted any rust (iron oxide) back into iron. It's quite a thin paint, so it's very easy to apply, and covers really well. It dries quickly, but I left it overnight before recoating it, and then left it a further 24 hours before I gave the chairs a final coat of standard Hammerite paint. Now that I've done all the work, the chairs seem fine - in fact they look better now than they did whey they were new! Time will tell if the Kurust really has cured the rust problem, but for now at least, I can honestly say that the paint appears to have done its job quickly, easily and without any real fuss. This bottle (500ml capacity) has let me cover two chairs twice over, so it's actually quite economical. There's a tiny amount left in the bottle, so I'll hold onto it and see if it keeps until next year when I might try it on other metal objects that have also started to show signs of rust. By the way, I was initially very confused when I was searching Amazon for Kurust - there was a massive difference in price - I paid around £10 for this bottle, but I saw the exact same item on sale from other vendors for more than double this. I initially thought there was something inferior about this particular item from this particular vendor, but if you take the time to delve deeper, you'll find it's the same; don't necessarily assume that you get what you pay for. As long as it's Hammerite and called Kurust, I would personally buy from the cheapest vendor on Amazon that you can. Overall, this is a great buy. I hope you've found this brief review useful.
