MG Chemicals - 4887-454G 63/37 Rosin Core Leaded Solder, 0.05 Diameter, 1 lb Spool

Works awesome! Melts instantly and give youa clean solder joint

Solder does the trick. Helped me solder up multiple light fixtures on an underground wire run before sealing the connections in rubber. Solder melts nicely and doesnt spit when heated. Worked great for my application and the 0.05 thickness was the perfect size. Nice price too.

Excellent

The flux seems a bit on the heavy side, but it flows great and makes solid joints. I save the silver stuff for delicate digital, or sensitive audio applications. For everything else, this is probably what you want.
