sorry if repost, didn't see this expressly answered.
today i noticed some of the paint on my front bumper is flaking a little. just wondering what you guys suggest as a fix. now it's not a show car, so it doesn't have to look amazing however i just don't want it to peel anymore. you know? peeling =

my dad suggested take like a knife and scrape off the paint that's still losely attached, maybe sand the area very lightly and start slapping some coats of touch up paint on it.
what do you guys suggest?
thanks ahead of time
