Great product
Really easy to apply by brush. Once the loose rust was brushed away this stabilized the rust affected area. Brush also cleans in soapy warm water easily which I was surprised at.

Works but leaves hard residue.
Does what it is supposed to do. You only need a tiny amount as it does leave a hard residue that you then need to pick off.

Good product
Seems to the job very well. Easy to use. Haven’t see a product from these guys that isn’t too notch yet. Also give a really good shake before use. I ended up with a quite a thick layer of semi solid at the bottom of the container. I think my own fault for not shaking it enough.

Excellent product
Applied to the rust on the under side of my Rover cleared it completely and then sprayed over with their wax product, perfect looks like new - no mess no need to clean off following application and then seal coat

It’s the go to product for brush application
It works. Refurbishing underside of my old bmw 2 seater. Finished with a cheap Matt black anti corrosion paint. 3 months later not a sign of any surface rust

A+
Throughly impressed with this stuff. Over the winter just gone the awful sealant Audi use gave up and started falling away from the subframe allowing some surface rust to form which was unfortunately picked up at an MOT. So spent a day wire brushing everything and then applying this and the result is amazing, the subframe looks brand new even before a layer of black under seal went on. Time will be the ultimate test and I’m not a mechanic by any stretch but definitely idiot proof in its application. I recommend a set of cheap foam brushes for applying, tried a normal paint brush and some in a spray bottle but as soon as it starts drying they are unusable.

Teuer aber gut
Lässt sich gut verarbeiten und funktioniert gut als primer. Langzeitwirkung bleibt abzuwarten, sehr teuer
