So yeah, I'm making an Oppo license plate border, Here's what I did so far.

I first krazyglued all the cracks together, and let that cure for an hour outside.

I then sanded the surface, may need some advice on making a smooth paint finish without the relief of the lettering showing up, and I'm not sure if I should go black or white as the background colour.

I also made a template for a future version of the border on some scrap aluminum. I'll cut it out sometime later.
