I wouldn't worry about it too much.
My 72 was WELL USED in its former life, and it has the battle scars to prove it.
I used all of the tricks, a rivet in some dents, a decal over other dents, some paint and filler covering a few, bedliner in other spots, big patches covering big holes, and the aluminum that shows is kind of rough and not polished that great..
Still, I get lots of looks, photos and compliments from folks who can look past a need for perfection.
The red covers dents, the black bed liner covers more dents....
When perfection is not in the cards, camouflage is good....
