John, I usually treat the area with baking soda and water.  You will see
the acid bubble when this is neutralizing it.  Once you do that you can
clean up the rust and paint it.  I have done this many times on the past
and it seems to hold up well.  I use rustolem paint and primer.  If you
wanted to get really crazy you could use to Zinc primer which you can
buy at Walmart.  Hope this helps,
