if you are going to rust repair in these areas, the best thing to do is remove
both of the trims marked in color and also the glass. it it very easy to get them
all out and then the rubber strip under the lower trim comes
off. 1 unscrew the latch, 2 remove the vertical trim edge on the B pilar,
3. open the window and prop with a 2x4 to hold glass out 3".
4. pry out the rubber vertical seal to see behind it, 5. remove four very
small screws under the rubber, it does not come off at this time as it holds
the glass too. 6. pull window out, 7 remove rubber window seal that goes
around top, back, bottom of glass, 8 both of the trims have aluminum rivets
which hold them in place, slice them off with a cold chisel and hammer,
9 do the horizontal first and then the vertical.
under the vertical you will find perfect example of the original color if the
car was not repainted. it should take you less time to do this work than it
took me to type it with two fingers.
good luck and update with pictures.
