The best solder in the world! have been using it for 25 years now. Be careful, liquid flux is VERY strong. So be extra careful with it. Wash your hands often. I've done some very complex soldering work with StayBrite ie micro. 030 dia Custom piano bow...here's a neat trick. Use a regular marker/ink as a resist to prevent the solder from going where you don't want it. After soldering, wash off the ink with alcohol and continue. I prefer a Weller soldering iron rated at β 100-125(?) watts (no less and certainly no hotter than a gun/iron) and a micro flashlight.
