Just something cheap like this or do you look for ones that advertise as flux (borax?)? Do you mix with de-ionised water or denatured alcohol (like this?) to make a paste?
Just the standard stuff and council juice to paste it up. I've been using it for years, as have most of the old boys of frame building. Got onto it after Winston Vaz did a lol when he heard how much I spent on the cycle design stuff.

That's the type of advice my miserly heart loves to hear!
Does boric acid flux paste dissolve in warm water after use?
