Man, was this panel more frustrating than I imagined it to be.  The dimpling along the bottom edge from the countersink tool was tough to smooth out.  I hammered it out as best I could.  Then filler and sanding.  Several times, I went too far on the sanding and was back to square one.  Finally, I got a smooth film on there and walked away.  Here are some shots in various stages of completion.  NEW!!  The bottom 2 pictures show the 99.9% completed panel.  I had to touch up a few blemishes but it turned out great!  Check it off as done!
