This appears to be a superb product for car chassis coating
Leaves surface rust coated in a black layer, that presents a excellence finish for chassis etc. easy to apply with a brush or from hand sprayer.

Appears to do what it's supposed to.
Working on an old series Land Rover so there was plenty of surface rust underneath. Turned rust black after half an hour so seems quite effective. Have over painted so time will tell. Company are based in Germany but delivery was pretty quick considering present circumstances.

Excellent value. Plenty of product.
Used to attack pitted surface rust on vehicle chassis. Leaves a coating on corrosion when dry. This layer is the rust stopped and converted, neutralised ready to paint over with a suitable sealer. Similar to a popular item stocked by motorist outlets in the uk but better priced and larger quantity. Helps keep my old VW,s on the road!

Best rust treatment I have used
I originally bought this for the rusty patches under the car and found it to be excellent. I now use it on all sorts of rusted items after cleaning the metal the best I can and applying a finishing paint. It can stain non metal surfaces if spilt though.

Best I have used
Nothing to dislike, it's outperformed everything I have used before . I used it on landrover chassis and its as good as it says it is

Works
Seems to work as long as you paint it afterwards. Easy to apply on most surfaces but can run off vertical surfaces like the side of chassis rails. A spray applicator or foam roller may be better than a brush. If you have a large project this is a great purchase.

good
very good stuff, but important to protect existing paintwork. Goes a long way and converts the rust well.

Ottimo
Non posso paragonare a altri perché l unico provato,l ho messo su cerchi in ferro che ormai erano color ruggine invece che neri, sono diventati come appena pitturati senza carteggiare,una spazzolata di ferro veloce e via....ho trattato con 2 mani senza verniciatura finale e rimasto stupito del risultato una volta asciutti, poi questa primavera a marzo quando li smonto se non aggiorno è perché la ruggine dopo sale e neve non è piu apparsa come descritto ,..ora trattamento meccanica sottoscocca tutta velata di ruggine, per un risultato liscio e perfetto al tatto e occhio fino ovviamente bisogna carteggiare,non scioglie ma penetra.... top

Eficacia contrastada
Convertidor de óxido. Lo he utilizado para sanear los bajos del coche. Ha quedado perfecto. Genera una reacción química y convierte el óxido en un polímero. Se puede dejar tal cual. Yo, sin embargo, pinté encima y la pintura se adhiere perfectamente. Recomendable.

TOP QUALITY
Top quality finish from a great brand. I used it on a rear underbody of my well surface rusted car and it did a fantastic job. Very easy to brush on and great finish. I was able to spray paint Shultz onto it once dry to give it an as new finish. Highly recommend this product. There is enough in this bottle to do many cars.
