Here’s a really cool PC Case mod, a DIY on how to make mirror-finish PC Case surface.
Spray paint your PC case and give it a mirror finish.
You won’t need expensive painting equipment and supplies.
You’ll find most of the products I used at hardware and
3M Perfect It III Compounds and 3M Imperial Hand Glaze is usually sold in Autobody Supply Stores, but I’ve linked them to an online resource.
I prefer using carnauba type car wax, but any automotive wax will work fine.
Regardless of wax used, you must allow paint to cure for at least 30 days before applying wax.
