The connector for my rear defrost, the little clip that is soldered to the glass, broke loose. I'm wondering if there is a specific soldering agent I need to use for this, or if regular silver solder or JB Weld will work? I know all of it will hold the thing in place, but I'm thinking conductivity is an issue.

Thanks in advance.

 

Hmmm...googling around it appears there's an electrically conductive epoxy on the market. Anybody used it? Preferable to solder?
