FMJ is actually a sealant made by CMA (Blackfire's owner) and they license the use of Menzerna's name. I have it , and when you consider a blind test and cost of product their are many other better alternatives. We did a blue Malibu about two years ago, and every panel was different. None of the five of us picked the FMJ. If memory serves, Poorboys EX-P was initially the most liked.
