Hello Donna,

    My-T-flux is not really designed to be a protective coating flux.
    The benefit of a self pickling flux is to keep the metal clean
    inside joints while soldering, especially if the solder job is
    taking longer than planed. Also the joint will clean up easier after
    soldering incase you don't get the solder to flow the first time and
    have to go back (yuck). 

    As for the pitting it could be a lot of things such as over heating
    the solder, pickling to long, quenching in pickle to soon after
    solidification, re-flowing the solder joint while soldering
    something else on the piece. Strong pickle is hard on solder joints
    so be careful about leaving pieces in to long. Also, if you can see
    the pits in your solder seam try using less solder, a good joint
    requires very little solder. 

Hope this helps,
