Rust in '78 Midget

["Vince J. Pujalte" <pujalte@stic.net>]

Hello All!
  I own a '78 Midget which has a slit-like rust perforation beneath the 
bottom hinge on the body for the driver's door. I am a compulsive 
sort, but trying to remain grounded in reality. I have treated this 
perforation  with rust convertor. Must I remove the wing to arrest the 
rust's progress? I don't want to be crazy (or irresponsible). Any and all
advice from experience much appreciated.
