This is my first instructable, so let me know if something is not clear.
A few years ago, I found a cover that I really liked, but it was twenty or thirty dollars. I'm a tightwad, so I found fingernail polish that looked similar to the holographic quality of the cover and painted the phone with it.
For four dollars, I had a phone that looked like the expensive case.
The nail polish stood up to the wear for months before I removed it and changed the color.
