As far as witness lines or ghostshadowing as I call it , that it always a concern with any joint, EVEN lapping metal& welding or filling a license plate hole against the recess instead of cutting & butt welding.
The thing that is in my favor here is that the joint is at an intersecting angle (approx 45 degrees) as opposed to a joint running across a flush panel. It will look like a line anyways, so hopefully it'll be extremely minimal. I planned on using USC all metal filler at the joint to smooth the transition as opposed to lite body filler.My local supplier was out, but I'll probably wait or order some foe the extra peace of mind.
