That's a very good point! It's the little bottle of liquid flux as much as anything else. I've now switched to Novak Racing Silver solder which is EXACTLY the same stuff at StayBrite but you get more of it. And the little bottle of flux from StayBrite goes a long, long way. So get yourself one of the StayBrite kits about about three packs of the Novak silver solder (from Tower).
