I hat that because sometimes you will actually grind hot metal right over these pin holes, and while the final surface looks good, there is still actually just a tiny bit of rust under there. Even through, however, if you do the repair well enough, yes rust will come back, however it will take SIGNIFICANTLY longer to "rot" out your car then if you were to just leave it be. Are you planning to keep this car for a really long time, do you want to do a REALLY good job and make SURE you will not have to "re-restore" the car after another 10 years or so? If this is the case, I would go all out on it and spend whatever it costs to get it back in shape.
