I started at 2% by weight..... Went down to 1.5% and the gain in C.O.R.E. was still there (very little) and the lube cohesiveness was a lot better than at 2%. I tested back and forth with and without hBN.... Finally just left it out. I don't want to breathe it either. It a really fine particulate.
I second NO MOLY!!!! Lamar likes it though!
