cottonseed, Chris from Worthington Assembly here. We've actually reflowed proto boards here with a hot air station. The trick is to get the whole board warm first and then target the gun (or pencil) at the joints. You can use a hair dryer to get the whole board warm and then use the hot air gun to quickly reflow each joint. It's pretty fast and works well. If you bump the pads like you mentioned with a little solder, you can then flatten the joints very carefully with a flat piece of metal (but end of a small screwdriver or something similar) and then apply a little flux, and then warm the whole board and reflow as mentioned before. Works like a charm!
