Knife making Heat treats, Anti scale compounds, Clean up blades and RC testing

Has anyone else used Condersal Z1100 anti scale compound. I had high hopes for it but they were not realised first time round!
The knife making continues, now the knives get their anti scale compound, then into the kiln for the hardening and tempering.
I'm not pleased with the anti scale compound Condursal Z1100. It was the first time I tried IT.
normally I use an anti scale compound called ATP641 which gives me much better results.
I did manage to clean the blades up in the end but it took me a lot more time and effort
Finally we measure the RC value
