It is a personal choise, I live in Australia an my 42 one and half ton truck is staying the way I brought it 8 years ago with surface rust but no dints so it looks as original as possible. After rebuilding it and now doing the wiring the only up grade is from 6V to 12V electrics and still no new paint. I LOVE IT cant wait to drive it.
Like everyone has said its your toy do what you want
