Alan, here was my fender mount.
You can see the small piece of black electrical tape I have where the coax goes up the side.

That piece of tape stuck there for over two years.
After I took that mount off, I had no scratches left over from it or the coax.

Here is with the hood shut all the way.
There is a pretty good gap so the bracket itself did not scratch either the fender or the hood too.
