Hello Maurice,

there must be a reason why there are different Bruennier agents for ferrous/steel metals and non-ferrous metals. Perhaps the difference lies in the different effects on the metals. The durability/longevity of the bruennier layer may depend on this.

We should consult the all-knowing Internet on this, or try to find technical literature similar to that of Dennis. Experimenting is expensive and costs a lot of time. Searching for literature may be too. Staring into a crystal ball will not bring us any further...

Many greetings

PS: I just saw, ScorpioNZ seems to explain us with contributions from his book. Many thanks for that Dennis.
