Any Suggestions for fixing this Scratch?

[Towley]

My beautiful Mazda 3 BP Soul Red Crystal has been defiled!

I am so upset someone has scratched my car , apparently in a shopping centre car park as that's the only place I can think of as it wasn't there before...

Nothing I can see on my Blackvue Dashcam points to the culprit. I even have parking mode enabled but maybe it wasn't sensitive enough to detect this scratch.

"46V Soul Crystal Red is a complex three-layer red pearl, which unfortunately isn’t something we can repair as a mobile service. This type of paintwork needs to be done in a panel shop."

I have been quoted $800 AUD to basically respray the whole car door.

It's a bit hard to see whether it's just scuffing or not.

Might try a random-orbital dual-action polisher, with appropriate pads and chemicals. I've taken down a great number of "scuff" type imperfections and even minor scratches. So long as the "scratch" is shallow enough to not actually catch a finger nail as you test to see how deep it is, there's every chance of removal.

$150 for the polisher, $100 for the chemicals, $50 for the pads, plus an hour to attempt the polishing. Then you'll have the gear to keep for future such imperfections and light polishing. Good tools to have.

From pic that looks really light and small.

Before going full in on the polisher and stuff recommended by GFrosty, try some Nu Finish Scratch Doctor. I have used it on much worse looking scratches and they came out.

If it is deeper and the orbital doesn't work then maybe some Dr ColorChip repair.
