As for coatings, I wish I had submitted my 3MK-1800 test to Aardenburg without the spray... and he's not taking any new samples, at least for now.
Just to make sure once and for all, here's my earlier sample of the mottling, before I made the correction in my 2% dilution: I don't know if you saw it over in the QTR Group. Now, as I say, it is barely visible.

Thank you so much,
