Thanks for all the ideas guys.
I went to a automated car wash where I used to get the rover washed to see
if that may have whacked it.

I could have sworn the nozzles came down toward the windshield and hood.

This trip thru that car wash the nozzles stayed up and away from the hood and roof.

But, my memory on these details is scantly. The nozzles are about 1.5 to 2" round. With the windshield all full of water and soap, no way to see what is happening. I used the wipers today to see what was happening and the nozzles were not near the truck at all.

In looking at the marks closely, looks like perhaps a crow bar used to whack it as each mark has two deeper gashes - like a crow bar would have.

Plus the marks are canted out at an angle about 20 degrees from center.

The car wash is exactly 90 degrees perpendicular to the hood.
So, perhaps not the car wash.

But, then there is a scraping too. The car wash may have scraped it.
Or, the crow bar guy thought about ripping the paint and then figured just wail on it.

Oh well.

I was looking at how people get dents out.
The hail dents coming out with dry ice has huge truth to it.

Here is a demo.
My dents are too small. But a big dent - here is the proof:

 

Those are not dents in your hood, they are a story.
All Rovers need a story, mine has several, yous has at least one now.
Color them with a paint pen and call it good.
