Do you want to brush your iPhone’s chrome bezel and give it a steel bezel effect? All you need is some tape and a sponge with a rough edge on one side. With the sponge, you’re going to remove scratches and give the iPhone’s bezel a nice shiny steel bezel effect. The tape is needed to protect the screen and the back of the iPhone. The video explains it more clearly. The result is better then I thought.
