Thanks for the write-up! Some observations from my install:
- I drilled holes through the fascia and backing trim and threaded the screw straight in. I bought edge clips but didn't bother with them and the hold seems fine (with 3m tape of course)
- I bought mine used, so I'm not sure if this is a common issue. I had a couple millimeters of body color still visible behind the splitters upon installation - very noticeable on white.
My solution was to get some pinstriping tape (I had a graphite color on-hand) and tape the area behind the splitter.
Successfully closed up the gap!
