I need to solder one brass nipple onto a stainless cable, so I need this special Phosphoric Acid Flux (as in the link below).
If the space doesn't have any, do any members have a drop I could borrow?
It seems a bit un-eco to buy a whole bottle just for one job, then never use it again.
If anyone is an expert in this black art, please  let me know!

rLab definitely doesn't have any.
