So my review for occasional use over the years.
The scope of Brunox Epoxy is very limited. It is very difficult to estimate, from which amount of rust does not protect the product and have rather the opposite effect.
Brunox has a Phophorsäureanteil which converts the rust into iron phosphate. The red rust is then first black, which many users find great. This black layer (the name in almost similar way at a middle Fertan created) but is also the problem: the user can not see whether under this black layer is not further rust is present, then twice violently erupts again after overpainting. The product is geeigent as pre-primer for very light rust, no means for splitting and shaving, because it does not begin to creep well as indicated. The term "rust" should be taken seriously wirklch.
