I want stuff to look nice. I don't want it to look like I just pulled it out of an old truck in the junkyard.. If I can clean it to suit me, I leave it. If not, it gets cast iron color high heat paint.

Some castings are smother than others. I've had some Glide cases that were nice and cleaned up well.

Oven cleaner and elbow grease. I don't like to glass bead that stuff.
