133 PCS Sanding Disc Drill Polishing Kit Sanding Attachment, 3 Inch Wet Dry Headlight Restoration Kit, Hook and Loop Sandpaper Buffing Pads with Rotary Tools for Car Wood Metal Glass Resin Expoxy

Pull that cracked section back forward by reaching in below and behind it, then polish it with a microfiber towel and part of a $15 bottle of car polish, and maybe a cordless drill with a drill polisher attachment something like this: https://www.amazon.com/dp/B0D5QMZ335/ It's not a critical part, it's all plastic, so there's no risk of further damage or anything. It's purely cosmetic.

It won't be quick. It is not easy. With power tools, I'll step up to 2000. By hand, I step up to 4000. Then I clean and dry before using a polish specific for resin. I got this one for my niece. It works pretty well. Using power tools is a huge help. By hand will take forever. I also got this kit for my niece, she loves it.
