Hi,

on my 83 300D, in my rear passenger side door, I have been getting a rust bubble. It is on the front edge of the door, 3/4 of the way down, where the metal goees in a bit (there is a little ridge).
It was there since I bought it, and after last summer, the paint got a bit iffy. There was a small pinholeon the paint, and every time d press in the area of the bubble, Id hear a crunchy sound. I eventually went over the hole with some touchup paint (letting the solvent get in there to help evaporate out the water). the paint wouldnt cloise up the hole, so I used crazy glue instad. The hole was quite small, more of just a sliver, but I managed to inject a bit of crazy glue in there and then use it to seal over the top, overwhich I painted with the touchup paint.

Now the actual door edge-side of the bubble is raising from the rest of the metal, and so I can see long pant cracks on the edge. The rust bubble has been contained for some time now, and hasnt gotten crunchy to the touch as it used to be, but I have noticed a bit of growth lately.

Is my door panel doomed? What is the best bet for preventing this from going further? Will I have to cut out and reconstruct the area? How difficult is this job goingto be? Can a good looking blended spray job be obtained by a DIY without professional spray tools?

Any help is most apprecated.

JMH
