Ever used this?

Saw some "Gel Flux" today. Apparently its used for soldering flux on stained glass windows. It says it works for lead, tin, ect. Says it doesn't burn or smoke.

Wonder how it works....anyone know?

it is probably the equivelant of rosin core solder flux.
i doubt i would try it unless it was free.
