What are the possible steps to take in order to fix this nasty problem before it gets any worse?
Can that be sanded down and repainted in a matching color and (if done properly) be impossible to detect that any work was done?
Will metal work need to be undertaken? I understand it may be difficult to tell how bad it really is with only pictures. If I get in contact with a more car savvy person, will it be necessary for him to remove the panel to make sure its not corroding from the inside?
I'm most likely going to get the car up on a lift to look around the entire undercarriage, I'm quite frankly a bit worried that rust may have crept up in places I just can't see.
Thanks in advance for any input you may have.
