I understand what you're saying Jamie but who has time to sweat the small stuff?
I bought a bottle of Tank Rats "Black4Tracks" and tried it this morning on the tracks for the Hummel. Boy did that stuff work good or what. All those silver spots I was getting with "Blacken It" are gone with this soup and that's worth a lot to me.
I can finish a set in a day now instead of three or four using the other stuff. Here's a picture I took after they were dry and ready for my oil washes and pigments.
If you try it I think you'll like it too
