A belated thanks (again!) Dave. Now that I know what I SHOULD do (remove the fender, etc...) I have to figure out what I CAN do. Without time and especially space to fix this properly, I'll probably take your suggestion and try to unearth what's behind the seam seal. Any suggestions as to what I should use for a sealer? Also, if there is a sizable gap due to rust, what kind of filler (?) could I use?
