Car keyed with a friendly message

My car was keyed a while ago. I regrettably tried to fix it with touch-up paint and made it worse. I don’t think the scratches are really even that deep. What’s a good DIY way to fix this properly? I want to sell this and get a new car, but I don’t think anyone will buy it like this.
