without destroying anything,especially the board,
Have you used those HORRIBLE PPS capacitors that melt if you so much as look at them funny ? Evil bloody things.
and different solders/parts need different heating profiles (preheating, heating, setting, cooling)
It can be hard to match that profile with any repeatability with a hot air tool...but it IS doable :D
Like Sean says, I can't see why it wouldn't work, if you are careful. Its a bad idea to dump too much heat into the board too quickly - you can literally crack SM resistors and capacitors from thermal expansion.
