Here is my suggestion for badly corroded cap jobs,
Again this is my suggestion, might not be yours, just sharing from my hands-on experience.
make sure when you do the se/30 that you just don't mess around and twist off the old caps, don't try to heat them up and remove.. just twist the bastards off, if you lift a pad doing it , it was going to happen anyways. but unless they are mostly corroded off, you will not have any issues with pads.
if you have a buffer wheel for your dremel its good to polish the pads once you twist them off, it gets the corrosion from the leaked electrolyte, makes better contact with the soldering iron. makes your life way more easy when putting the new ones back on.
Flux always helps the solder flow it helps make your life easier.
