I was pleasantly surprised by the many suggestions how to get rid of a
stubborn coating layer.
I chose to follow David Weinshenkers advice and checked out the protosar
website. Got the hydrochloric acid and the glycerin.
Since three days, the mirror is soaking in this solution outside.
Outside because I do not want to inhale the fumes of the hydrochlric
acid, and I don´t have acces to a tight vessel. Outside temperature is
about the freezing point.
The coating is gone now on about 20% of the mirror area. The solution
has dissolved the layer only where it was already scratched from
previous attempts with abrasives.
I´ll keep you informed...
