Nice work.
You can always do more; did you....
AIO the door jambs?
AIO or seal the wiper arms?
Chase down every RID that was safe to remove?
Lube/dress door seals?
Edge every panel and raised body line?
Customer was clearly happy, you're getting more work out of it, and you (hopefully) got paid fairly for the work you did; no shame in any of that.
When you're trying to make money, you're OCD needs to be kept in-check as a function of your market. There is a relatively small market for full-on OCD time and cost but once you're in it, it would be plenty to keep a guy busy in the right location; back off your OCD a bit and the market opens up a lot.
