I will have gallon of Kester 979 flux, but that is way too much for me and I want to sell most of it at cost.
979 is a replacement for 971, and is an awesome flux. It's VOC free, huge plus if you do your SMT work at home.
16oz(1 pint) is $5 plus shipping (US only,) which should be around $5 as well.
I may also do 8oz, which should be ~$6 shipped (US only.)
