Yes it is true, oxygen is needed for rust and moisture is the most common way 
that mosture is present.

If you do not get to the bare metal and start the process of positively 
sealing out oxygen right at the  bare metal, then you are going to be more 
likely to have oxygen get to the metal.

Note, there are compounds that claim to turn rust into a primer so you can 
paint over with no rust removal.  The U.S. Navy experimented with these and 
found that over time they fail.  However, for emergency at sea repairs, they 
are used, but when the ship gets to port everything is then removed to bare 
metal and good quality primer/paint is used.
