I hope that wasn't ACID paste!


Alan: "Plumber's Solder Paste" is PROBABLY acidic, but mainly, it is a
"paste" made of tiny spheres of solder-metal. It melts/flows with usual
soldering heat, and is "painted on" the bright metal before heating. If used to
"tin" a bare copper surface, it is WASHED OFF before electronic components and
"rosin core" solder is used!
