Last summer I drove the Fish in a rainstorm... I found out the hard way that I had holes in the trunk. I thought they were just a few misc bolt holes that needed to be plugged, but found a problem in the left rear wheel well.
I'm really worried about hitting rain while going to MATS so I needed a quick fix.
Here is the problem area and a picture of light coming through from the trunk.
I'm not a metal worker so I thought I'd fill the gap until such time I can get it fixed properly.
I used paper & cardboard coated with vaseline (so the filler won't stick) and taped it to the gap in the wheel well to make a form.
I did the same from the trunk side and used the cloth to hold it in place.
Sprayed the filler and sealed the gap.
The next day the filler lost its mind.
Job done for now.
