Mg Chemicals 835-100ML Liquid Rosin Flux

I work on old electronics and this is great for soldering those direct to the chassis.

I work in a factory and use this to repair solder jobs all the time. Works great.

Some of the best flux out there, really helps get good solder coverage on the joints.

I worked making pacemakers for a while and good flux is key for good solder coverage. This stuff is better than what we used in manufacturing.Price is good to, even better.

Much better quality than other flux out there. Truly does the job well, but make sure you have proper ventilation.
