Sorry to hear about that, it just seems like its one thing after another on your car! About removing the access panel for the gas tank, I would suggest dropping the tank as well. When I removed mine last month, I found a good sized area on the inside wall of the frame under the brake cylinder that had rusted. I chipped away all of the bubled epoxy to fortunately find only surface rust. I bought the starter pack of POR-15 and it was pretty strait forward to apply. The starter pack comes with everything you need for a 12 or 15 sq foot area. This was more than enough in my case. I painted the rusted area, and put the gas tank back in. I can only hope its doing what its supposed to. In an case, good luck tracing down any rust you may find on your frame. Jim Reeve MNDMC - Minnesota DeLorean Club DMC-6960 > 1.
