After reading many many posts I understand most of the products bond on the molecular level. I have a black envoy and seems like whenever I use the NB it just doesn't want to cooperate with the KSG. I use very small amounts of each and just barely use any of the KSG. The surface looks good with the KSG but after the NB it's almost impossible to remove the swirls. Maybe I'm doing something wrong or maybe I should try the Zaino's...dunno. I read the twins may have a new recipe:nixweiss , either case I bought mine last summer if that matters. Can I skip the KSG and use something else after the AIO....should I try the Zaino products?
