I have lots of soldering rework to do on old corroded PCB's, i desparately need rosin flux but the only one available from RS or Farnell is a rosin flux pen which is too dry to be of use, do you know of a wetter rosin flux pen or where i can get a bottle of rosin flux?
Chemtronics CW8200 is a pen form that doesn't seem to dry out (I have had a couple of these pens for 2 years).
Not sure about bottled flux though, I saw this URL but no idea if it is any good : (
