I replaced Buffermount with NTMT when I could no longer source it easily. NTMT is made by D&K Coatings who bought out Seal/Beinfang. I can't remember if I could tell a difference when I first switched over , but I think they are practically the same. In fact, I may like it even better. It is certainly offered at a much better price. I buy it from this place: http://artgrafix.com/store/page151.html
