Personally, I like the honesty which those particular dents represent. Those dents were earned during earlier times when it did work.
I wouldn't touch them, in fact I may put some dents like those in my daily driver beater truck. It must have been babied in an early life and earned nothing like yours did.
In the short term, I am leaving all the dents alone. The truck has lived its life as a truck and shows it.
In the long term, I would like to have some nice paint and I will make an effort to fix as much damage as I can to go along with that.
