Yes, I put it down to luck. It was shallow and about knee sized so I'm very happy it sorted itself out.
My grandfather was a panel beater, opened his own shop just after WWII.
I used to love spending time at his shop as a kid. All the old cars and the smell of paint was a kind of heaven for me. Great memories.
The guy I get to fix cars when I need it done these days is very good.
There is an art to it, that's for sure.
