It might look straight now that it's faded, but that is most likely not the case once the paint is shiny.
Its never as easy as scuff and shoot if you want it factory nice or better.
In the past when I painted someone's car and they didnt want to pay for top notch, and said just mediocre was fine, I would reject the whole job. It's either top notch or nothing because that B or C grade job will reflect on you.
It always needs body work to be nice. Otherwise rattle canning is fine
