Got it. Thanks. I started to take out the old patch today. After I got through the thick layer of black roofing caulk, then the layer of white sealing caulk, I found the numerous shodily done spot welds. I am trying to figure out the best way to remove them.

I also grinded about 1/2" of putty off of the rear valance. Who knows what the previous owners were thinking w/ this car. It's quite the hack job. I am putting way more into it than I originally planned.
