    I use the lead free
    fine electrical rosin core solder & extra flux paste to get things flowing...
    96% tin, 4% silver
    Would you go flip my truck back over??

    If you are new to soldering, I'd suggest a standard 60/40 tin/lead composition. Lead-free solders may be saving our world but they can be harder to use. Additionally, though silver solders are better conductors, a good solder joint is much more important.
    I much prefer liquid flux to the paste type.

    Thinking about the life expectancy of any RC product, the slight corrosiveness associated with flux products should not be a huge concern.
