Is there an equivalent to conformal lacquer that can be purchased at the big
box hardware stores?

Another trick is to spray the board with conformal lacquer before
soldering. Direct application of a soldering iron will burn through the
lacquer allowing you to solder but accidentally brushing against a track
won't. For surface mount components you will have to tin the pads to
burn off the lacquer before mounting the components.

lightly sand the board to remove rough edges on the milled areas which helps
the solder pull away from the isolation cuts. One way to avoid problems with
bridges is to avoid narrow isolation cuts under components during layout of
the board. It is fairly easy to fix bridges that are easily seen, but when
under components they are very difficult to see or fix.
