I need help with some issues on my 2000 Honda (read Isuzu) Passport.

1)The two rear passenger doors are VERY stiff to open. - It's almost like
they are glued to the rubber door sill. The sills are crumpled over at the
top rear corner of each door. Could this be a cause?

2) Proper lubricant - Also, what is the proper lubricant for the thin metal
bar that connects the door to the frame? I've tried WD-40, but that does not
last very long.

3) Tar like substance - I also have a tar-like substance oozing out from the
bottom of a couple of passenger doors, as well as the rear cargo door.
Anyone know what might be causing this?

I live in Maryland and only drive 100-150 miles a week back and forth to
work.



TIA,
