Blending clear coat ?

Thanks katnip.
I value everyone’s input to this point, and don’t doubt the wisdom and experience everyone has had along these lines.
One thing I find myself trying to figure out (just for the sake of doing so more-so than for my decision making) is most say if you try to blend clear coat you will get a hazy line where the blend is, and the more time that passes the more distinctive it will be. I don’t question this. But what I don’t get is what creates that hazy line, and why don’t you get haze under clear coat over clear coat if you do an entire panel edge to edge?
The only thing I can figure is with the blend you don’t ever get a true “joining” of the clears at that point (no matter how much blender or “melter” you use) and you get moisture (oxidation) that permeates the blend line? One would think you would still get that doing a whole panel at some point. even if you “wrap” the edges of the panel are the two coats of clear ever joining?
Still don’t know what I am going to do. Here is the spot. The pics don’t show the scratch. Just show that I was stupid enough to think I could wet sand and make it look less noticeable :blush:
