To "buff it out" try to fill the chip/scratch with paint, and slowly build up the level to the surrounding paint. Dab/fully cure/dab/repeat. Avoid getting a lot of rouge paint on the surrounding clear. Once the paint is cured you can try to wet sand with 2000 grit, use a block to sand flat, then buff with a rotary buffer and compound.
I found an online tutorial, and I am floored at how much better it looks, almost brand new. My bumper actually had a massive scrape through the primer, into the vinyl, and I was going to pay someone to fix that. I can't believe I almost paid someone hundreds of dollars to fix this... 2000 grit wet sand, meguiar's ultimate compound with a cheap drill attachment I had from a headlight restoration, followed by a wax. It looks really good... And it was so easy!
