None of the mechanics and engine rebuilders I keep in contact with ever use a sealer. I suspect the plug was either poorly installed, or the surfaces not clean, or both.

Though it's tempting to go with brass if you can find them, I'd recommend steel as the originals. Whether it's electrolysis or differences in coefficient of expansions, brass plugs seem to be much more problematic than steel.
