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.
Review: Excellent rust killer - Good stuff, it goes a long way. Only buy what you need. For example, rusty car boot I only used 5% of 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.

### ⭐⭐⭐⭐ Works Well but expensive
*by M***E on 20 December 2017*

I bought this to repaint a tractor transport box which had been sitting outside neglected for many months. It had become very rusty overall and rust had deeply penetrated scores and scratches. After wire wheeling and scraping I used this product to convert the surface rust before priming. It seems to work very well indeed. The rust turns black and slightly glossy. Applying the product is dead easy - it is very thin and has a pink colour so you can see where it has already been applied. I used a small brush and it only took minutes. Painting after using Kurust is easy. I used a spray and brush on primer after using Kurust without any problem. Initially, this product looks very expensive (circa £34.00/L) but you are buying in a small quantity and paying for the Hammerite branding. I am very surprised at how far the product goes, I used about 1/4 of the 250ml pack on approximately 16 sq.ft - in fairness I could of used about half the amount I did (slap it on method!). You are meant to apply only to the rust but I literally just slapped it over the entire surface, a bit wasteful. Conclusion. The product does seem to work, it turns red Iron Oxide into blueish Iron Tannate by using Tannic acid and a polymer. I am absolutely certain that there are no 'magic' ingredients in the Hammerite Brand that are not in cheaper alternatives. From what i read products containing Tannic Acid have a short shelf life (about 9 months from purchase) so it is probably best to buy the amount you need when you need it. Recommended? Yes, if you just have a small area to treat. If you have a large area or multiple projects to treat then you can buy 5L pots of rust converter for less than £5 per Litre, this branded small pack works out at about £34 per Litre. The shelve life put me of buying it in quantity - no point in having 4L of expired chemical to dispose of. Hope that helps ;-)
